Allow disabling grouping features

[babakfp]

Hi

What are the benefits of having this feature?

1. It would make this menu clean and readable:

2. It bloats the UI:

The way that I use this app is, I copy and paste 100s of urls into the app. Some of these urls automatically create groupings that bring no benefit.

3. I never use this grouping features. It makes no sense. I switch between urls all the time. Urls stop working all the time. Some times after a few hours. So, all the time I add and delete urls.
