Really, I thought that was the whole point of Themechanger's ability to install parts of themes without the whole enchilada like other themeswitchers. What's the deal with all those little checkboxes in the right window, if not to take parts of themes and leave others? Just to mix theme's with Aqua? Yuk! Definitely make it an option. You can never have too many options. The Aqua backup thing could be expanded into a 'Save Custom Theme' function so once you get the right mix you can save it off and get it back. I'm made a custom theme that's a mix of MMX elements, Brushed windows, AluminiteX widgets and sliders and a bunch of other stuff. There might be other people who can't do decent themes, but can at least play mix and match!!!
