[REQUEST] Use theme in banner and options

[cpuccino]

Describe the solution you'd like Any chance there's already a built in way to change the banner colors to the theme selected? Or maybe just print it out as text instead of ASCII art. The banner doesn't match the theme that i'm using at all right now (nord), cheers

Maybe naive additional. It would be good to add keybinding for toggle theme. For ability change theme on the fly, w/o menu. It will be useful for estimate themes without cover by main menu block and also w/o fade colors.
