Hi, A remaining thing to clarify is how to handle these restrictions in relation with the Nesting feature.
* For visibility restrictions, I believe it is safe to continue with the current behavior, that is to show the template provider in the specified location (space) and its children (subspaces). * For the default creation location, this does not apply * For creation restrictions, we need some consensus. Do we also allow creation in the children of the specified location restriction? ** This can create problems to the usecase when you use this field/restriction to make sure that an application properly reads the new entries by restricting creation to a specific space. If you were to allow children, the app would not properly read the new entries. Sure, you might say that the app needs fixing, but, depending on the app, it may not be possible. ** On the other side, in general templates (or for templates of apps that support nesting), allowing children for the restriction might be needed. *** Note that currently (recently implemented) we are allowing the creation in child spaces of the existing restrictions. ** Should we have a 4th "allow children" option, a boolean/checkbox value, to control the behavior of the creation restrictions to suit both major cases? Of course, we will not be able to have more complex settings (like 2 spaces with children and 2 spaces without children), but we could accept this limitation since it would probably be an edge case anyway. Another note on the differentiation between visibility and creation restrictions is that, in terms of UI, it would require some reworking, since having 2 trees in the same UI is not a good idea.
