I finally resumed work on the MR that allows for a non solid background in #phosh's overview. There still some lose ends, but it's progressing:
@agx Makes a world of difference. Will there be an option to have the overview background and regular background be the same?
@baconicsynergy Initially these will even be the same. Lockscreen wallpaper will be different.
@agx super cool. Thank you for the hard work!
