How to reproduce

• Set up an item display
• Switch to spectator and start following another player
• Have the player look at the item display from another angle

Result

Expected

Opening this as a tracking issue (I'm already working on it).

Many of glowcase's packet handlers don't check that the player is in creative mode, has permission to edit the glowcase in question, etc.

Additionally, the packet code is needlessly complex. Sometimes a roundtrip is done to the server for something that can easily be done on the client (like "opening the 'open url confirmation' screen").

It would be cool if there was a block where you could insert an image URL to show that image in the world, with options to align or resize the image (maybe also an option to change the aspect ratio with different resize modes)

It's also really hard to read the URL behind the item (but the url is shown again on the confirmation screen).

In Packages I just manually translate backwards and render text in a darker color, instead of relying on the vanilla text shadow.

I don't think these should be implemented now (too big of a change too late into the event), but maybe for next time?

• Rethink the mailbox. I like the idea of sending private messages to players while they're offline and the diegetic interface is kind of cute, but I think it makes more sense to have a /mail command that sends a message to a specific person or people (instead of a specific coordinate with a mailbox on it), and then show messages on login, or with a /mail check command. Or it can be removed.
• Maybe - remove the rotation blockstate on the Item Display Block and Text Block, and convert it to NBT. The blockstate is not necessary since these blocks render everything with block entity renderers anyway. It leads to complexity where all the properties except for rotation are stored in the nbt, so sometimes you have to mess with the blockstate instead of just the nbt, and blehhh
• Some sort of rotation offset for the Item Display Block. Sometimes I don't want the item to face directly at the player because the angle is weird, but I don't want the item to be totally stationary either. It might also be nice to select different display contexts too (not just FIXED).
• Something that looks like an arrow, where you're able to customize the direction and color to some degree. Currently I've been putting the Gravity Changer API arrows inside Item Display Blocks.

Thinking about some needs that come up time and time again across various build servers:

• A way to access the vanilla container locking system without needing /data permissions.
• A source of infinite items and/or a trash can. Infinite droppers and dispensers.
• A chest where players can open it and look around, but they actually copy each item they take from the chest instead of removing them. (it's like having a bunch of item display blocks in a small area.)
