[Feature Request] Support to filter by Open Type Features

[nitramr]

Is your feature request related to a problem? Please describe. Right now, I would like to filter fonts by their open type features. In an example, I want to know which fonts have a support for petite caps, historical ligatures or alternative variants of characters.

Describe the solution you'd like Add a new filter in manage -> category for "Open Type Features". Group all fonts by their supported open type font feature.

Describe alternatives you've considered n/a
