I apparently can't comment because I don't own rimworld, and therefore don't have rimconnect, however, I wanted to leave a few comments from the perspective of a "watcher".

The first, and possibly largest, thing that would make the addon so much easier to use would be collapsible categories. This would allow people to filter out all the extraneous possibilities while they browse for something they may want to throw at a streamer. It's one thing if I know I want to send a weapon, I can just search "weapon" and see everything that has it in the title or falls into that category. That simplicity isn't available if we don't know exactly what we're looking for. If we want to peruse the options for shenanigans, we need to see most of the things, so maybe just sorting out "items" would be handy.

Super user-friendly option would be an option to hide what we can't afford. This could help with someone that just wants to blow through 500 points quickly, but doesn't want to have to filter through 1-5k items.

The addon is super fun, just wanted to give a couple thoughts from an end-user.
