Tap's group and taps list

i just want to add new idea , in brave they add the tap’s group and some times we need group in the group like:
-1
.1
.2
-2
.1
.2
that’s my idea about tap’s group just add that we can make group inside the main group to manage the taps.

another note i suggest to add like a list to prevent the taps to be small just like a ‘x’ only i cant press on it easily and make it optional to user. I hope that my first post is read and taken into consideration thank you <3
