well, where it really shines is if you for some reason need the ability to run a windowed application, and or feel a need to or want to, but with the absolute minimal crap possible to make it run.
you install square tiles and can put them along the edge of the screen in order you choose, set the single or double click to launch, right click them for other options, i think the entire thing weighs in at under 16 megabytes.. it's pretty epically brilliant..
one could think of it as a framebuffer to run xterm inside of, but nearly as responsive as a native TTY VT100 terminal.. no bloat.
as the young hoolingans say, 'fa'sho.' hahahaha. but yeah its rad. i've used it for years. it is the fastest window manager, hands down, minus like that other one that doesn't do much by modern standards, i forget the name, but oh rat something.. super old
