I just thought of a nice feature that I haven't found implemented anywhere yet. I think it would be nice to have an option for icewmbg to act as an xconsole replacement, so that the user can see console messages in the background without running a separate task.
I would imagine an unobtrusive look that tries to blend in with the theme background, maybe even a semi-transparent font if the server supports transparency.
If I find a little time, I will look at the source code of both xconsole and icewmbg and maybe come up with a primitive patch, but don't count on me not being too busy.
Thanks for this great window manager, I really like it!
