Description -
Person A is editing a scenario. Person B starts editing that same scenario.
Person A saves the scenario with changes. Person B then saves the scenario with changes.
Person A's changes are lost. Person B was unaware that Person A was (1) actively editing and (2) had saved.
This is a common problem with online tools. Some suggested solutions including (1) tracking user activity and warning other editors that someone else is ALSO looking into the file and/or (2) warning a user that someone else has saved the scenario since the scenario was opened for editing and that changes might be overwritten and/or (3) allowing an editor to "lock" the scenario for a defined amount of time so they are the only ones that can edit.
Why is this feature important to you -
The "simultaneous overwrite problem" is real and has forced us to have to re-do work.
How would you like the feature to work -
Ideally, I'd like for a simultaneous edit canvas like Google Docs provides. But I'll accept some type of warning and/or "lock" behavior similar to what Microsoft Sharepoint provides.
Current Behaviour -
