Would it be possible to have Guides that are set up in the first Scene, added to all Scenes?
We may add a way to propagate guides from one scene through all other scenes in a future update. In the meantime, you can copy guides from one scene and paste them in other scenes using View > Guides > Copy Guides and View > Guides > Paste Guides.
Thanks Ryan, I didn't see that option before. Pasting them works perfectly for me.
