I've setup my screenlets exactly the way that I want them, but I don't have a quick access to any of them. The screenlet config offers me the following : keep above,below, sticky, locky, widget.
Out of these only treat as Widget seems to be of any use here. I just looked at this in detail and thought it was what I was looking for. It might have been a workaround for the issue (instead of minimizing I would just press F9. But this means that the widget hides itself from the normal desktop, which is not what I want.
What I want is that on pressing Ctrl+Alt+D or Super+D, I should see the desktop with my screenlets there. I don't want them to minimize with the rest of the windows.
As a final struggle, I've thought of a solution using compiz to declare the screenlet windows as non-minimizing, but surely there must be a better way than that. (Instructions for this would be helpful as well - I'm not sure what to enter in the rule matches)
