Unlocking a form

What causes a form to be locked and how can i unlock it?
I was importing some forms from a previous app and this message came up when trying to delete a form.


There’s a form property called ‘locked’. It’s useful if you want to lock a form’s layout so you cannot mess it up by accident.

Sorry, i don’t know how i missed that.

If i import forms, does that in any way slow down the overall app compared to if i made them normally?

Imported forms are no different than forms you make in AppStudio - they will be the same speed.
