Sometimes you want to create a new version of a certain page or microflow (or other element) and once done, replacing the current one with the new version while still keeping the old one (e.g. with a different name (_OLD) or excluded). The new element should be used everywhere where the original was used.
To accomplish this you should be able to select an element (e.g. a page) and have a right-click option to replace it with a different element of the same type. This should replace is in all places in the app where it's being used.
