       - adds a '-h' option which sets the minimum height of a dmenu line
       - this helps integrate dmenu with other UI elements that require a particular vertical size
 
+   - [managed](https://tools.suckless.org/dmenu/patches/managed/)
+      - adds a `-wm` flag which sets override_redirect to false; thus letting your window manager manage the dmenu window
+      - this may be helpful in contexts where you don't want to exclusively bind dmenu or want to treat dmenu more as a "window" rather than as an overlay

    - [mouse-support](https://tools.suckless.org/dmenu/patches/mouse-support/)
       - adds basic mouse support for dmenu
