It can swallow applications so you can have a clock, a load monitor, eyes, etc. up there. More importantly, it can be configured on a per-application basis, and communicate with the program by sending key events. The window manager can recover its state on a restart. If you're like him, the mlvwm isn't for you. Floating windows don't get the floating pallet look.
All configuration is done be editing a text file with sometimes cryptic syntax.
Feel free to use my mlvwmrc file as a starting point if that will help. The menubar sits up there eating up 25ish pixels of your screen and isn't necessarily very useful. Copyright David McKee 2000. All rights reserved.
