I was so excited for the reveals feature on Maps, but some of the sources link to the correct books, but worst of all, the image takes up the entire screen and can't be interacted with except to close. When you share it same thing for the players, takes up their entire screen. That is NOT helpful AT ALL. It's not in a special space for reference later. Just BAM image and then as soon as the DM closes it it's gone. TERRIBLE implementation. Absolute garbage. Please find a better way to do this.

For the record, I LOVE Maps, it's been really amazing so far honestly. I use it all the time. So this feels really frustrating for something that could have been really awesome and it's so poorly implemented (in my opinion, I know). Thank you for the hard work you do already and I sincerely hope you can adjust this somehow for a better experience!

Was hoping for Dm layer or dynamic lighting, got send players a picture instead. Boo

To be fair, nobody announced Dynamic Lighting...

Whatever problem causes avatars and character sheet backgrounds to disappear, also affects the new Reveal items so that I get an error.

I don't understand why we can't just reveal any image in any source we have? Nothing from the planescape books are reveal-able which is really disappointing given how helpful it would be to be able to show images of the city to players going there for the first time.

Hm. A good start, but it still needs some work to be really useful. Here are my suggestions.

1. ability for DM to pre-select/flag images for later use.
2. ability for DM to upload custom images. Similar to the ability to upload custom maps.
3. image indexing needs to be improved. Search feature is very hit or miss.
4. need a way for players to save images for later use. Maybe a way to easily port displayed images to the campaign notes section.
5. image captioning/tooltips to help identify and select images. Those thumbnails are pretty small!
6. many important images are missing, such as NPCs from The Wild Beyond the Witchlight or the Dryad from the 2014 MM.

BTW, I can no longer find the feedback tab in Maps.

Thanks.

To add on to the feedback here:

• Custom Reveals - This is the big one.  I'm paying for 10GB of space and the reveals only appear to include things from official materials.  I'm both adding more flavour to existing campaigns, notes, scenes, etc, but when I'm using 100% homebrew campaign stuff, the reveals is essentially "not a feature".
• Adding a ⭐on items, or a folder we can choose to move stuff to, so that we can prepare for a game.
• Alternatively, it would really nice to have all the items I've favourited in either clickable buttons along the top, or a separate drop down menu away from the massive list.
• Nice to have: Put the caption of the item below the item when viewing it in the browser, and a toggle to show or hider the caption to players. 
• Some of the reveals comprise two images together, and they can't be split to only show one.  e.g.

  https://media.dndbeyond.com/compendium-images/dmg/Bk0e1TBRN0uPvprV/10-004.bastions-over-time.png

Things I appreciate:

• The list is always filtered to "what I own" instead of trying to wave stuff in front of us.  Would love that to be the default for the Monster browser.

Planescape’s absence seems to be an oversight. I’ll let the devs know.

 Thanks!

Reveal isn't a bad idea; execution is well to be desired. In my opinion reveal could have been useful if the DM/GM had control of how much was revealed at a time. Perhaps the players only see the side view of the zombie, the part that isn't rotted away. Or they only see the crest of the long fin that runs down a dragon's neck. Also, smaller images would have been a better call. Nobody wants something that takes up their full screen. Speaking of Maps here is a few ideas. Why not allow the creation of maps without having to create a campaign? For me Maps seem like a wasted opportunity for the creation process. Let the DM create their whole campaign with Maps and reveal each of them as their campaign unfolds. This would be good for homebrews and for DMs like me who don't follow an adventure module to the letter. Or put the maps at the front end of campaign design. 

Honestly, I would have loved it if the use of Maps wasn't directly tied to setting up a campaign first or selecting for a preload.
