It's possible to delete the Output module [FIXED in v1.7.4]

[GreaseMonkey]

1. Select a module that isn't the Output module.
2. Press the Delete key (or select "Delete Module" from the menu).
3. While the "Are you sure" box is open, click on the Output module.
4. Click OK.

Confirmed on both Linux and Android, so it's probably doable on all versions.

Pretty minor as I've never triggered it accidentally, but if you're looking for bugs to fix, there's an underlying bug you might want to tackle.

Ok. Thank you.
Will be fixed in v1.7.4
