Theme Missing Hidden Tags Icon
I started using rEFInd and loved the Maia theme. Noticed it's missing the func_hidden.png
for the Hidden Tags menu item. This also is an issue for the upstream regular theme, but a very kind user submitted icons in the same style that never ended up making it in.
Side note, thought it would be worth mentioning that someone has picked up where munlik has left off to continue updating the original regular theme. It includes the icons submitted by d4k0.
Thank you very much for all the efforts.
