Would love to have the ability to actually detach files from a Central Model. Right now you can fully detach and create a new local file ONLY if you discard previous work like worksets, views and sheets which is completely asinine and nonsensical. Would love to see the feature included where I can detach files from a central model and PRESERVE worksets WITHOUT creating a new central model. What's the point?! If I'm trying to detach to create a new file, why are you forcing users to create A NEW CENTRAL MODEL that's always looking for its past references and save location? It's completely contradictory, especially when any file can be turned into a central model. It makes no sense I have to discard worksets in order to create a standalone file that is actually detached from central. Please please please solve this. Really the only reasonable option is to be able to detach from central period and create a new independent file with or without previous worksets. If I want to preserve worksets and make a new central model, I can do that myself after the fact. Right now the only, messy, option you are giving users is to copy model elements from one file into a brand new fresh one, and we all know how unreliable the copy/paste function is in Revit.
Please make it as easy to roll back making a central file as it is to make one. Currently you have it extremely easy to make a central file, but no real way to roll that back while preserving work that's already done. You can and should do better.
