Add "None" Edge Type & Custom Subtitles Fonts Import

[ealor7uh]

Describe your suggested feature

I would like to request the following features for the project:
• "None" Option in Edge Type — Add an option labeled "None" in the edge type dropdown menu. This option should allow users to select no edge style.
• Import Custom Subtitles Fonts from File — Provide a functionality in the settings or subtitle customization menu that allows users to upload and use custom font files for subtitles.

Other details

If needed, I can provide further details or assist with testing these features. Thank you for considering these suggestions. 😁
