Tony Stratton let us know of a few things that are planned for Style XP Beta 4, it is not released yet, but they have put up a product page (link below)
Choose to have Style XP run in the system tray for easy management and selection of new styles, or turn Style XP off for zero-footprint operation. No additional memory will be utilized unless you desire it.
Style XP skins are zero-footprint because they use the same Visual Style Source that is built into XP. XP"s Visual Style Engine will load and draw our start button with the exact code used to load and draw the infamous green start buttons of the original Blue, Olive Green, and Silver skins.
This is done by performing an in memory patch to XP"s Visual Style Engine. Style XP does not use SetWindowsHookEx, which can noticeably slow system performance. Nor does it hook the "Appearance" tab on the Display Properties property sheet.
