What functionality is missing? What is unsatisfying with the current situation?

So it's not as if we didnt have quite a few icons, but when you get down to it, there is so much more that we could have with not so much effort added as far as I know. Icons are THE most important thing to keep things organized in a visual way, and having restrictions leads me and I would think quite a few other users to develop workaround about it, but is that necessary? On the exact same page I can find RPG Awesome Icons there is so much more that I could use, but WA doesn't recognize them. And Font Awesome Icons has a whole bunch too, but there is a lot that isn't there. I will put the examples where this feature has been a pain to get around.
I have a tab which is called "Equipment" where everything that is wearable in my world is, there isn't a single icon for an arm, having then to use "robotic arm" for something that is clearly not meant to go there, now to not give the pain I will give a list of things I need that are not part of the summarized icons we have access to:
- Arms
- Back (cloaks, capes)
- Slings
- Slingshots
- Darts
- Variety of Shields
- Flails
- Quarterstaffs
- Variety of Helmets (such as leather caps, hats like sallets and such)
- Variety of Boots (Leather, cloth, medieval shoes and more)
- Hand equipment, such as gloves (metal, leather and cloth)
- Chest armor variety (there's just "vest")

And really there is SO much more to list there, but I just went over 1 of my folders which are about 40, I'd say I have an icon that works well about 50% of the times, which hey, it's not bad at all, but I would love to have it be closer to 80% or even be 100% which is very hard, of course, I can give some reccomendations of packs if devs want me to, though I do not want to clutter it too much, but in Iconduck.com there is so many icons that fit WA style perfectly. I'd love for that to be introduced here, we could even get colors if it were a possibility which would be amazing to tierize stuff, such as with let's say flowers, there is common flowers, uncommons, and so on, a chromatic icon system would help a LOT too and make WA even a greater tool for writters, as well as DM's and video game creators.
