Hello everybody!
I'm sorry for leaving this app unattended but I was in some kind of hurry here..
For the ones asking about the width:
yes, I'll code something to fix/address that, user-defined width (in % of screen) or something like that.

Regarding multiple instances:
What about having more than one line so that it's one command per line..
If you select only one command, one line.. two commands.. two lines..
etc.. what do you think?
