Last night I tried actually using workspaces, and had some problems. ALT -Fx to move between them was OK, but moving the current window to workspace x with C-t Fx either didn't work or made Ratpoison hang - just the wallpaper and the mousepointer visible, but nothing working, including unclutter. The same when I tried to move up a workspace from the top. This should presumably either go to the first workspace, do nothing, or do nothing and generate an error message.
I changed it back to C-t just to make sure it wasn't because of the key I'm using instead of the default.
Incidentally, the use I found for them was when working with two tiled windows (IDLE and Python book in Zathura) if I wanted to look at anything else without having to redo the tiling, it was easy to have two workspaces.
A minor thing - screensaver seems not to be there, is this intentional, or did I break it?
I put call to xscreensaver in .xinitrc, which works, but pops up an annoying message for a few seconds. Should I put it somewhere else?
