additional icon resources

[RaizePrime]

while i do greatly enjoy the current icon sets offered, i do know of a few other websites with various icon types.

https://nagoshiashumari.github.io/Rpg-Awesome/

https://cappuccicons.com/

https://boxicons.com/

https://icomoon.io/

some may be similar, but an implementation of any of these would be awesome! as far as i know, rpg awesome and cappuccicons are both completely free while the others have free/paid plans.
