Make SS real time?

We're currently using sheets that many people work in at the same time. We're constantly overwriting one another and for all we know, these are missed job opportunities that are never caught if we're not constantly going into each and every cell history. I'm aware that you have to save and/or refresh, but we're working in the sheet simultaneously so there is no way of knowing what cells someone is already in. Have there been any updates, or are there any plug ins that allow SS to update in real time?
