I know you are talking about Kmenu but there are several application launchers in widgets, have you tried any? maybe some can do what you want
The problem with these are that they depend on the same KmenuEdit.
If you change something on the one, it also changes on the other.
So, that doesn't help me.
Unless of course, something is not quite right here on my setup
Yes, I have tried both as at first I thought that's the solution.
I am going to put this one on ice for a few days or a week.
I have to think about this.
Forget about the ice and the thinking

I probably found a satisfactory solution .
That is, ....for me....not for noobie noobs

I will have to reinstall in a spare partition as I most probably am going to < nuke > a few things a few times.
But, it will be good fun.
If it works out, I will need some one ( like Leiche or Pinoc or <you> ) to write a small batch file
