If two contributors edit a process at the same time, there is no indication of a conflict until you save and get an error saying you can't save because you're not in the current version. An automatic checkout when you start editing, and an error right away if someone else is already editing, would same much time, lost work and frustration with using Promapp. Even a manual checkout would be better than the current state.
This feature is sorely needed, as some of our processes require collaboration between a group of Subject Matter Experts who work remotely and across time zones. We have had multiple instances where two Process Experts or Process Champions are editing separate sections of the process at the same time and they get the save error.
A check out feature (against the sections being edited), or a feature which allows live collaboration would be amazing
Just some helpful tips. I created our guide/framework to follow that eliminates this risk by showing ownership during creation of a new process and ownership of making edits to a publish process. Example: A new process developed is sent to Group Champion on confirm process workflow/mapping. During this time, the Process Expert knows they cannot make any edits. It works very well
