We already have a handy wheel for choosing emotions, and as many as 10 pages for more convenience.
But the general structure of all emotions looks very uncomfortable. Yes, we have a letter-by-letter search, but it obliges the creators of emotions to write not a name and description for their emotion, but to prescribe tags by which the player must search for the desired emotion. It's very uncomfortable when you have hundreds of emotions.

This is a processed screenshot for example

In this case, the system folders of the mod (such as emotecraft_export and server) are ignored

Also, the search has been improved, so I don't know about folders

Ok, I've started working on this, you can see the progress in the folders branch: https://github.com/KosmX/emotes/tree/folders

I've done everything I wanted to do, I'll do the merge tomorrow
While you have time to suggest something else.
Or test for bugs...
