An feature where if you right click something in the Activity>summary view, an dropdown list appears and you can select which catagory this Thing belongs to
What about something like this? Right clicking is not something that Activity Watch does out of the box, so I needed to create a mode button for it. I think this is more flexible than just having an “Add to category” button.
These changes can be found on my fork: GitHub - RTnhN/aw-webui: Webapp for visualizing and browsing ActivityWatch data, built with Vue.js. · GitHub. If this is something that people like, I can work on adding a new release. With the newest versions of ActivityWatch, you can just add an environment variable to a path and use a different webui instead of using the default one.
