To rid the nasty labels I will show the net result of doing so in th epic attached. Labels = Icon Charges as well and unless you are ok with no charge counter display, then simple deletion of the icon text is not a viable option.
Uhm... you guys all know that all you have to do to remove the annoying hotbar text is to just unset the keys in Controls section of the Options. Once you do that, the numbers you unset dissappear, and keep all other text such as poisons, etc...
BTW, are you planning an update to your Guild Window mod by any chance? It still works as is but I believe that it might be missing some new events or something minor like that.
