Fix:
- Custom apps is injected normally now. #64
- glue.css: Prior to this update, I had modification in preprocess that removed almost all glue.css files and referenced their links to zlink' app's
glue.csslink. This modification purpose was to prevent Spotify loading same CSS file over and over again. Since it was adopted by Spotify in client version 1.1.15, we don't to do this trick anymore. #67 colorcommand: should display all default colors whencurrent_themeconfig is blank.
