The Notes section on items is cut off. For example, the chain mail +1 has a stealth disadvantage but on the item list that is cutoff with just "stealth... ". No where on the item page are the Notes listed or explained.  Can we add the notes to the item page itself or even the drop-down on the item list?

It would be nice if selecting an item showed its full name in a smaller font. The massive list of Carpets of Flying left me confused as to their difference until I looked at the description and turned my phone sideways. 

If the listings are going to include each possible variation (+1 battleaxe, +1 dagger, adamantine chainmail, adamantine breastplate, etc.) than the description should really include the stats for the base item: damage, weight, properties, etc. And since magic items do have a base price based on rarity, I say include that as well (individual DMs can explain how they are handling costs themselves).

There needs to be an option to sort items by magical rarity, as well, I think. This would help facilitate DMs to find level appropriate gear.

I love the way everything is looking so far except for the items layout, I feel like this is such a wide open area that the first layout people see should be more intuitive.

Right away you're greeted with Adamantine &blahblahblah, you notice that everything is in alphabetical order and go to the "filters". I think this could be simplified by presenting this information in a different way, maybe a few simple choices that break it down for players building characters, DM's looking to provide treasure and then the third option would be something like "alphabetical list of ALL items, magical and non magical."

Also, it would be cool if you listed prices on items (I HATE this whole "magic is so rare you can't assign gold prices system. Then why are there SO MANY MAGIC ITEMS?!)

 EDIT: It would be helpful to have an items list that is exactly the items only available in the PHB as shown to players. A gear, weapons and armor table, not all combined but three different selections. I imagine it would be mapped like "Players" or "DMs" list, you click players and it drops down to New Character, All Non-Magic, All Magic... then if you click "new character" it goes to "Equipment" or "Weapons" or "Armor." Of course having an option to NOT HAVE magic items by default would help, to click and add those would be more useful for a DM than anybody else for the most part, players just get to beg to see them in the game and have their mouths watering on the keyboard. 

I'm not great with ideas when it comes to dissemination of information but I think somebody below this post might be cool enough to have the right idea, isn't that what Beta's are for?

There are quite a few very good suggestions in this post. I know that I am looking at this as a prospective DM who will be leading some friends into their first foray of 5ed.  I cannot begin to stress enough the level of confusion that ensues when I start discussing magic item "values" with players who have played 3.5 and 4.  We often have to break out our old rule books and utilize those as a baseline.  I am 42 years old, I don't have the time to sit and research and extrapolate projected gold values for magic items!!  If your fan base is already having to utilize previous rule books for magic item pricing baselines, or referring to 3rd party unofficial pricing tables, then wouldn't it be reasonable to present a  baseline price referencing pg 135 of the DMG for the items?  Sorry for an redundancy or ignorance, it's my second Monday in a row.

And VERY excited about DDB!

I'm using Beyond as a resource as I prep for a Storm King's Thunder adventure and hoped I could roll on a Magic Item Table.  

Wish this had tables from DMG with a "random item generator/chooser" button. Feel free to make up a story for the history behind each magical item too :P
