Ability on iPhone/mobile to drag and drop videos/media directly from Photos Library on to blocks/channels.

visual accessibility option in settings: I use black and white on my phone and can’t tell what color things are (green, red, etc.).

some sort of non color based contrast or indicator option would be awesome

On Sander on Safari its not possible to save images to desktop, either through Right click → Save to Downloads or drag & drop. I'm running Safari 15

Would absolutely love to be able to make private 'margin notes' on a block. Could be as simple as a visibility setting for comments

Show all channels in Safari extension. I don't remember all of my channels and have to open Arena up in a browser.

saving tweets is extremely unreliable :(

On mobile, explore page is laggy when scrolling potentially due to multiple gifs

Ability to pin blocks to the top of a channel

on mobile ability to upload multiple images
