LiteStep introduced these in much more interesting ways than explorer ever accomplished. First released in 98, but worked fine in 95 as well.

You could have them in the wharf(preferred IMO) or more standard widget styles.

Into Windows, as it is based on AfterStep and WindowMaker.

Yea, it was based on afterstep. But for Windows. I first used it in Windows 95. Cuz explorer was an unstable piece of junk.
