Select a folder for custom fonts

[AmadeusGraves]

The functionality to be able to select a custom font to change the webpage's font is very good, but I encounter a problem. 

When you try to select a custom font, it opens the file explorer, and this is a problem because if you have various fonts, you can't determine which font is the one that you need. 

A possible workaround could be from Einkbro, select the folder that contains all fonts and previsualize these fonts in the selector of Einkbro. 

A perfect example could be Moon Reader, where you can select a fonts folder and previsualize it. This selector also could have a search function to be able to search by the name of the font. 

I hope that my English is understandable; it is not my first language, so sorry for the inconvenience.
