When troubleshooting a subroutine or a region in Unilogic which has an MB or other register appearing several times in a ladder, I find myself scanning around a trying to recall everywhere that each tag is used and how it is used. To help make this process easier, I would like to suggest that there be an option where a temporary color can be applied to a tag so that everywhere it appears in the program, it has that color assigned to it. Perhaps if a user were to right click on a register in the ladder and then assign a color, it would color all instances. This way a user could scan down through a subroutine and see their MB's or registers highlighted the designated color and easily identify their tags without needing to read the tag or notes. When I think of it, we have region colors that we can assign, why not add teh ability to color tags as well?
