You have to get it right the first time. So be careful. You can't go back and modify, you have to save it over again with the modifications.
Thanks, Dave (just found that out...) Are they easy to delete and start again?
Sure, just drag the bad one to the trash in the OS.
Anyone using Essential Graphics to create a template for the first time and has messed up the controls, I've found the easiest thing to correct the problem is to simply duplicate the compensation you're using to create the template, then link the control panel to that duplicate and you can start over again.
I've written a feature request asking for more control over the panel, so controls that aren't needed or are added accidentally, can be deleted.
