Shell user interface refresh
With the upcoming arrival of libadwaita and the new application stylesheet, it would make sense to refresh the shell appearance.
The current design uses chunky borders, gradients, and an outdated color palette.
It also has visual inconsistencies, such as the different colors used for the dash (#3b3b3b) and search bar (#353535). There are also varying border sizes, mainly 2px and 3px.
Here are some examples of a shell theme refresh. The changes are minor, but tie the experience together. I'd like to see some development towards a new/revised look for the shell.
