the 't' is short for 'tiling'.
currently usable but somewhat rough around the edges.
mtwm is a quasi-manual tiling window manager for the X window system written with rust xcb bindings. it features a nudge function which allows one to stretch smaller windows to the edges of the screen using vim binds alt-hjkl and then revert nudged windows to previous dimensions using alt-r.
you may want to edit keybinds for your own personal configuration. they can be found under the KEYBINDS heading near the bottom of main.rs.
mtwm also allows for a startup script, located at ~/.microsof-twindows/autostart.sh. mine currently runs a ".fehbg &" and a simple dzen2 status bar script. don't forget to make your autostart executable :)
