dmenu is an efficient dynamic menu for X. This contains patches that I've added from suckless.org.

• border - Adds a border around dmenu with -bw borderwidth.
• center - Adds an option to center dmenu on screen with -c-flag.
• lineheight - Adds an option to increase the height of dmenu with -h height-flag.
• lines below prompt - Adds the option to make dmenu list lines vertically below the prompt with -l lines-flag.

sudo make clean install

Customizations are done in config.h, then run sudo make clean install to apply those changes.

See the man pages for details.
