Slide Elements as Background Elements
So essentially my idea here is for you to be able to lock certain elements and have them count as the background.
Let's say I have a line running through all of my slides, as a design element, and I want it to seem seamless. I'd use slide transitions-- no issue, change them both. But if I want to use a different transition for the stuff ON my slide, the line will move as well, the effect broken.
So, if I could say "this line is part of the 'background,' treat it as such" I could then make full use of the transitions-- and if this were the case, you could lock elements and prevent them from even being selected, which would make super complicated slides a lot easier to work with. Like right now if I lock something, it's "out of the way" but not really. If I had a "lock to background" button where those literally are just entirely locked there, and aren't selectable without unchecking that, it'd clean things up a lot.
Just a thought!

Interesting idea—thanks for sharing!
On a related note, we're considering making it possible to pin content blocks so that they are locked in place and remain visible on all Slides. That's not exactly the same as what you asked for but figured I'd share our thinking in a similar space.
