I regularly have quite large mxd projects, with lots of feature layers referenced in Table of Contents (TOC). For simplicity I group them together. The problem is that I can't see the difference between a feature layer or a group (or a group of groups).
It is not only me using these documents, and it would be really useful to be able to colorize the name of groups and/or feature layers or have any other way of separate them from each other (other than having to press the +).
At the very least I'd like to have one color for groups and another for feature layers, but being able to choose freely would be a big improvement. Then I can have blue for water related stuff, red for administrative, green for... you get the picture.
Is there any such functionality in Arcmap? Or has anyone made a neat add-in that could do this?
