[Feature request] Offline Import of Fonts

[Palloxin]

Describe your suggested feature

Pretty much what a lot of users would like. Yes you import it with css, but it requires internet, and if you stay offline afterward for too much the imported font disappears.

CSS import doesnt allow having a vast, custom list of imported fonts anyway.

Fonts should be importable only by selecting .ttf files.

Beyond the offline avaiability, this featyre shoukd offer the possibility to stack imported fonts, and be switchable very quickly, not like css import.

Other details

Extra fonts might go to an ulterior option in this place ↓, that will list ALL custom imported fonts (not in the horizontal list, but a button that if clicked should make a sub window appear with all custom imported fonts)
