Thanks for raising this issue!

As it stands I don't think there's much I can do. Assuming you are on tech.lgbt, we have 5937 custom emojis that need to be downloaded, loaded and displayed at once.

Technically a GridView would help with that but we'd lose the categories so postponed.

edit: My suggestion is to use the completion providers instead. Start typing :<emoji name> and a popover with results will show up

Thanks I'll definitely try this next time.

So I tried typing :<emoji name> instead but unfortunately that doesn't seem to be a good work around as it only shows me the first 3 emoji of 20 emoji.

I also noticed that Tuba locks up showing this dialog when I try to go back to my post from the emoji picker.

Maybe there needs to be an autocompletion delay (ex: 500ms, especially for servers with lots of emojis) added to that particular piece of syntax?
