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)?
