I would really like to change the brackets used in this column to the exact opposite - "()" used for subtitle and "" used for remix.
In the new build:
You will have 5 new columns which can be defined from Options > View.
The contents are rendered using the same format as used in the Rename files tool for a lot of flexibility.
The columns are available in:
-All tracklist views
This is interesting because maybe it should be a fully customizable column instead which can show various aggregated information, defined by the user, instead of just customizing brackets.
I'm marking it as planned to test if it can be done. Also performance must be tested so that it does not slow down things too much.
