Is your feature request related to a problem? Please describe.
In case we create a new instance or switch workspaces, we need to set up all theme properties every time.

Describe the solution you'd like
Just as we can export and import projects, we would like to have the same functionality for themes as well.

Describe alternatives you've considered
I couldn't find any alternatives.
