I've been trying, for years, to use treesheets (https://strlen.com/treesheets/) on my TDE systems, always without success: there's some weird problem with minimising to the tray, which I won't bother to describe in detail unless people want me to. I was hopeful that the recent mention of ksystraycmd might point me in the right direction, but sadly I still can't get treesheets to behave sensibly (i.e., to minimise to the tray when I close it).
The treesheets author, when informed of the problem long ago, said that it was TDE's fault; but I have always been unconvinced, as no other program I have misbehaves in the same way.
Anyway, I just thought I'd ask here if anyone is successfully using treesheets with the systray in TDE; if so, perhaps we can talk privately to see what you are doing differently that makes it work (I don't want to clutter the reflector unnecessarily with something that might not be a TDE issue).
