Some unresolved (but closed) 'maybe in the future' ideas can be found here:

https://github.com/ryanoasis/nerd-fonts/milestone/24?closed=1

Note that 'future' Issues are normally closed even if unresolved, to keep 'real issues' more visible.
This Issue here is to give them their visibility.

Requests for new Icons/Sets/Fonts will also be closed and moved here: #1095

Please do open an Issue here, as that eases later implementation documentation. But it will be closed when moved to 1095.
