What inspired this wish list request?
Trying to quickly figure out how many columns I'm currently trying to add to my model.
What is the improvement you would like to see?
I would like to see similar counter for selected columns to Filter Col Selector that we already have in Data Table's columns panel which immediately shows how many columns have been selected (also I would like this to be implemented on such a level that when I'm scripting I don't have to write this always myself).
Columns panel (total columns / selected columns)
Filter Col Selector (on distribution platform) (total columns)
Also if you wish to go a bit further, add total column count to col list boxes also (not exactly sure where this could easily fit though).
Why is this idea important?
Gives user quick information about how many columns they have currently selected in the platform's filter col selector.
