Categorize watchers

Hello,

I think adding a categorizing rule based on the watcher may be helpful. I am using vim watcher, I usually use vim for programming. So, I wanted to make most things under the vim watcher into the programming category. However, there is no such option. The closest I could get to this goal is making a regex rule for every file extension I am used to program in, which is clearly not productive.

Thanks for the time.
