Support for activity names

Firstly, thanks for the awesome app.

I noticed that in the insights screen, it seems to indicate that meditation is one of many activities.

I use the app for reading because it helps me concentrate on the book without worrying about reading for too long and missing out on sleep. It would be great to be able to differentiate reading from meditation and so on.

I know this differs a bit from the primary use case so I understand if the request is rejected. The app is goated regardless. Thanks so much.
