well, one thing i'd like to see implemeted will probably seem as odd to most people but i'd like to be able to use WB's recoloring feature to change the taskbar and start menu color individually. yeah, i know it's trivial but i'd like it. it can be done in other fashions, i know. i've done it

I'd actually go for some fine-grained advanced recolor options. Not so much element based, but perhaps some options that could limit the HSL shift to any parts of the skin which are within a given HSL range already. For example. right now if I want to recolor a skin to red, but the menus, toolbars, etc., are slightly tinted rather than being straight gray, I have to have all that stuff a funky pale pinkish-gray in order to get the titlebar/start menu red. What I'd like to be able to do is recolor only the strongly saturated parts to red, and completely desaturate the low saturated parts.

Probably wishful thinking though. Just gotta fire up PSP and do it manually most likely.

can you create gradient and other bizzar stuff with the opacity on Windows Blinds?   (haven't played with it in ages, since one of my friends had it, I never did)

I second Kyro's suggestion.  Having just two seperate hue shifts would rock.

Also . . skinning the command prompt. 

This may be out of place or all ready considered but backward compatibility with Vista and XP if possibile.

Thirded.

Now I never expected that!

Not a UI feature as such, but the ability to select skin library path like in ThemeManager/IconPackager... then persons dual booting can access their skins from the one location, rather than having to load them in each OS and duplicating thousands of files

Done.

And Zubish on tap.
