Hello, first of all love the addon, using it for a very long time now, thank you for maintaining it :)
Few improvements id like to propose:

1. Improve "Bag Break" feature
   Currently, bag break works only if you play around with columns. IF you adjust it so you have equal # of slots on every single row then you will not see any actual breaks.
   Example with break but un-even row amounts:
   
   Example with all equal rows (no break visible even though bag break is enabled):
   
   Solution to this is to add a space (configurable perhaps with a slider?) between each bag to differntiate between the bags easily, currently i find i have to hover over the bags to see a highlight if i want to place the item in the right bag
   Example:
   

2. (related to #1 - Custom coloring depending on the bag filter set, like gear, consumables, reagents
   Example:
   

Maybe this feature request fits here, please let me know, otherwise I make a new issue.

Basically, what we want is grouping the bag's contents into fluid virtual groups, easily, without much menu config.

There are more ideas on how to maybe realize this in this reddit thread as well: https://www.reddit.com/r/wow/comments/9f9v8r/is_there_addon_such_as_bagnonadibags_that_also/
