dwm is an extremely fast, small, and dynamic window manager for X.
This dwm version has a few patches applied to it:
The patch files are here only for reference, I patched dwm.c manually after the first patch.
I also put in a boolean in config.h for choosing whether the client title is displayed in the status bar. The included status bar script is based on w0ng's and relies on a custom font.
Update 07.12.2016: added productivity lock; press XF86_Find to lock the interface for 15 minutes. While locked, no tag operations are allowed. There is no way to suspend the lock besides closing dwm, so use with care!
