This is only a minor nuisance but perhaps there is an equally minor fix for it:
I am used to run my scripts by hitting F5, which of course also works for Zorro. The only inconvenience is that Zorro keeps opening new control panels every time I do that, which results in dozens of panels if I dont close them again manually or save and switch back to the already open panel to run it.

So is there a way to save those few extra clicks (which add up over time)?

This had to be implemented, and is not as trivial as it sounds because it needs interprocess communication. It's on our list.

Ok thanks.
Like I said its not a big issue but its good to know that the developers are aware of it.
