Currently it's a bit frustrating when you align all the panels and save the layout but there is currently a label mismatch, if you choose "all panels" it should switch to all, not your custom layout and your custom layout should show in the list with a name you create such as *animation, *Rendering, *rotoscoping, The layout option should also allow the saving of the visual state of toolbars if they have been closed or not so we can maximize the custom view with one button.
