Hi, thanks so much for making the 1280x800 two deck Traktor 3 layout. I was doing some editing and one thing I can't figure out is how to edit the "main volume" container size. It appears to be locked on the object size and clicking the chain looking button doesn't unlock it.
To change property size of an object is floating across the template pages you need to unfloat first, change the size, and then float again to desired pages.
I suggest start on page 1, make yor change, then float the object to desired page.
