Be nice if there was an Alias column that made it a bit more user friendly. For example an alias for a command like tar -cvzf myhome.$date.tgz could be "Back Up Home".

Not sure why you are using a tree view either as their are no children (or are they), at least disable of "paint root"

Frequency could use a Delegate to make it more readable, as it is this is barely more usable then editing a cron file with vi or emacs.

I like the idea though and think it has potential.

Thanks for stating this project -David
