I recently figured out how to add arbitrary selection screens to the edit watch face menu, and thought I’d share my process in case anyone found it useful - I published it at https://nthn.uk/blog/wfs.html.
In brief, the method comprises the following steps:
- extract the final apk from watch face studio into a folder
- modify the configuration file stored in the watch face to add more menu options
- add configuration blocks to make use of the new menu options
- creating a new apk incorporating this modified file
I hope this is helpful!
