 ## Changes from xcompmgr:
 
 * __inactive window transparency__ (specified with `-i`)
+* __titlebar/frame transparency__ (specified with `-e`)
 * shadows are now enabled for argb windows, e.g. terminals with transparency
 * removed serverside shadows (and simple compositing) to clean the code,
   the only option that remains is clientside shadows
-* titlebar transparency (and possibly border transparency) is on the way
 * menu transparency (thanks to Dana)
 
+The above features give compton a feature set similar to the xfce compositor.
+
+Compton has only been tested with openbox so far, but frame transparency
+should work with any window manager that properly sets `_NET_FRAME_EXTENTS`.

 ## Fixes from the original xcompmgr:
 
 * fixed a segfault when opening certain window types
