Is it? Given your computer resource limits, personally, I would prefer to do the clickbars vs the memory load the addons will do, when the ability to do the same thing is already being used by ISBoxer.

And I think the time towards making the clickbars is very comparable to the time to locate the addons, download them, put them in the folder, restart WoW, and then spend more time configuring them.

But yes. I mean to say make a clickbar for each one of your toons. Hell, make it "Grid-shaped" if you want, even with the grid colors...
