I, too, am a fan of gkrellm. I've been using it since I first put linux on my i8000. I'm sorry to see that it's slowly moving out of favor. I wish I could help with the development, but I just don't have the skills.
I do have a question...I've been trying to jazz-up the calendar/clock a bit by closing everything else down, making it bigger, changing the font, size and color, but I really don't want the calendar (which I want to be much smaller than the time) to be on top...There isn't any way to change that, is there (other than opening another, separate, instance with just the calendar)?
For those who think gkrellm just looks old and clunky and doesn't fit in with kde anymore, let me share my gkrellm [url=http://ubuntuforums.org/showthread.php?p=10255656#post10255656]here.[/url] If you feel like it, you can also leave me some advice on the little issue I posted about, too. ;) I recommend anyone using (k)ubuntu, or perhaps debian, and wants to use gkrellm, also read my post. I contains some important information (at least I think it is...).
Oh, I know it's been a year (more ;) ), but if you want gkrellm to behave on your desktop, select it as a dock in its settings, then go to your window manager settings and select to force it under all other windows - it'll stay where it is and won't bother you anymore (won't lose focus either).
You should've saved that theme! Wish I could help. :)
