Customized my @droidian install with some gruvbox and papirus icons. Looks decent than the default black theme of #phosh. Gradience worked like a charm for apps, small tweaks like battery percentage on bar were done with postmarketos-tweaks . The colors and backgrounds for droidian's phosh (phone-shell) shell was with custom gtk-3.0 css.
Feels comfy to me now, it is a bumpy ride but it is Linux Mobile yall!
