I think the main problem is that dwm cannot dynamically adjust the number/name of tags. I find it very hard to keep track of the number->application/task mapping in my head. I could change the names of the tags to meaningful names, but then I would end up with task(s) that have no corresponding tag - and I'm back to confusion. I have therefore implemented a patch to allow tags names to be changed dynamically. It basically allows commands to be sent to dwm by setting the DWM_COMMAND Property on the root window (in the same way that the status text works), the first letter of the string is the command. Currently only N is recognised, and changes the name of all the selected tags to n(<str>) where n is the tag number, and str is the remainder of the command string. I could not find a small shell program that could change a named property of the root window, so wrote my own (also attached). Example usage: xsetatom DWM_COMMAND NWork-dwm with tag 2 selected would cause tag two's name to become '2(Work-dwm)'. Setting the command to just N will cause the names of the selected tags to revert to just numbers. I have a nice little dmenu script so I can type in new tag names, and find it very useful. This patch allows other commands to be easily added (see runcommand()). Tom -- Thomas Spurden
