Feature description:
I would like to suggest a feature to select custom playback buttons.
Problem solved:
More customization
Brought benefits:
Even more personal experience
Other application solutions:
BlackPlayer added a bunch of alternative button embedded to the app by user request. You could allow user to select icon in SVG or PNG directly from filesystem as workaround.
Additional description and context:
I can help you by providing tons of icons in any format and size since I’m using full version of icons8 application.
