Honestly I hate having to click on view other sources.  I wish the full list was still there and when you removed sources books you didn't even alphabetize them.  Also Guild Masters guide is missing from the list.  I would have liked to see any discontinued books like volo and mort tome of foes be removed only.  This has actually slowed down my finding the right source.  A quick drop is to speed that up not slow it down.

Looking at the full list of sources, I do think I understand the rationale behind their ordering. Core books first, then more setting-specific books(like the Guildmaster's Guide To Ravnica), then the discontinued books, then the translations. As for deciding which books remained on the "front page" as it were, I'm sure they did some looking at the website stats to see which books were accessed most often(that's definitely what I would have done). No ordering was going to be ideal for everybody, sadly.

biggest thing I want is a filter for ONLY books I own on DnD Beyond when im looking up items and monsters. Its so annoying to either have to sift through content I cant look at or manually input my books each time do a search 

 Yes.

This.

A thousand times, this.

The fact that they haven't provided a very, very, simple, big, obvious button called (wait for it)...

My Library

shows very clearly that they care more about selling us new books we don't want than making it easy for us to use the books we own.

Changing what (unowned) books I see on the Sources pulldown is rearranging deck chairs.

DDB has always prioritized selling books over making it easy for us to use our purchases. It's this way in the encounter builder, it's this way in the Search bar - it always shows you stuff you don't own to try and get you to buy something else. This is clearly motivated by a PM at WotC who wants to show some metric going up and to the right.

Exactly! It sucks that monetization is priority 1 compared to consumer happiness/ease of access. 

WoTC could compromise by making "My Library" and have some sidebar/tab that says "XX amount of monsters not shown due to unowned books. Show these results?" To incentivize people to buy books while also giving us a succinct list of content we can actually use

 Navigation Updates

While this alleviates the immediate problems, we do not consider it a long-term solution. We will continue exploring ways to make navigating our site easier and hope to give y'all the ability to personalize that experience in the future. For now, this change will allow us to make sure we can always keep our latest content where it's easiest to find - so keep an eye out for New! labels which will be presented in yellow text.

Any updates on when the "ability to personalize" part might happen? Is it actually scheduled in some form, or is it existing only as an ephemeral 'future issue'? /pos

Like many other people commenting here, I would also prefer to collate my own Featured lists, either by marking certain books as favourites or by having them automatically populated from the books I've bought. For example, I don't need the Basic Rules listed there if I've already bought the PHB and DMG. Why would I want to use the free source (which is missing things) if I've purchased the full content?

In addition, a huge amount of the menu is taken up by published adventures; this is a waste of valuable space. Even if a campaign is run entirely off of published content, a DM rarely needs more than one of those open at a time and a player is usually fine without any of them. The Featured Adventures section should therefore be, at most, one column; it would be much more useful to give Featured Sourcebooks three columns, as this is the content that most people will need to access most frequently.

I suggest sorting filters : By release date, By title (A-Z), with a checkbox to see only the products we own. 

Under Featured Sourcebooks, I feel the Sage Advice Compendium should have its own spot under or above "View all sources"...  Instead of "free", subtitle could be "Official Rulings (Q&A)" or something like that. (i.e. it's not a sourcebook).

 Seconded. With how vague some of the content in 5e is, it's very important to be able to find the Sage Advice (preferably very quickly, because it can drastically slow down gameplay).

Quote from AndrewDB >>

I understand the need to sell products, and the role that profit plays in the longevity of this service. So if you leave the products section as a full list of products sorted by most recent first in order to give attention to current marketing efforts, then maybe at least give us better UX by styling books we own and books we don't own differently. That would make the list more skimmable for users trying to find what they own, but also probably increase sales slightly by calling out the items we haven't yet bought and prodding the completionists.

If you keep the list of source books sorted by most recent  and popularity, then please add a user sorted list of source books under the collections part of the menu.

Finally, when you make these changes to the mobile / hamburger menu, please stop using line-height when you should be using margins. It looks silly. Margin collapse exists for this very reason.

 Absolutely seconding all aspects of this comment.

Come on guys it's about time you Add a feature that lets us filter books that we own it's so annoying Having to manually filter out content not owned when looking for stuff >:(

Quote from Oridith >>

Is it at all possible to, like the mobile menu, display already purchased sourcebooks/campaign modules at the top? Or, at least, have sorting options to display only purchased content?

Please!

Ability to filter only by owned content would be great, as looking at my real shelf. 
If not at the Mega Menu, at least at the Sources Section.
If not filtering, at least shadowing not-owned content (it'd encourage to buy the shadow content BTW). 

Thanks!

To start out, this section should be your library, not a marketplace to show books you don't have (that's what the Marketplace is for).  This dropdown is a duplication and would be better suited being renamed as "My Library" and removing all texts that the user does not have access to.  This would make finding materials much easier.  I've also seen other comments regarding favoriting or personalizing the order of the books and would agree to the benefits there.

"Favs" or "pins" of most used source material would be great. Would help to streamline game play, instead of long pauses while DM or player searches for content.

Come on Wizards get your act together! your not the only guys on the block for RPG content. piss people off to much by dragging your feet on Development and people will go else where. Where the development department actually listen and respond to their subscribers!

Seems easier where you can look up something specific, rather than scrolling through to find it. Also, the view all buttons make it easier if you want to see more. Also It would be nice if there was a place where all the "free" sources are. That way people can find them. 

Also might be easy for people who own un-free stuff if you add one where it's only books you own.
