So what's worth installing?
Anything that's likely to have issues on Win 7 64 bit?
Nope, not really. Theme Manager
Mangler is a bust as is DX 4(3.90 beta), other than that, it's all good. DeskScapes, WB's, LogonStudio, DX3.5 and WFX are working fine for me, Icon Packager, mostly working, most of the time. Go for the whole enchilada!
