A Top Bar builder that can be placed above a header and that never sticks. Problem is that if you want to add a top bar, you have to duplicate your header and make it sticky in a way that is not so nice, see this video: https://www.loom.com/share/612a68c48d1e452c8c3859e7644b773e
A Top Bar Builder would solve this because a sticky header wil recognise it and keep the appropriate distance to it.
