Also viewing
It would be helpful if there were a "UserName is also viewing this" notification if you open a job or try to edit an invoice/work order/estimate that another team member is using. We have had situations where edits were lost or communication crossed when two people were in a file at the same time. I do appreciate that multiple people can use a job at the same time, but a shared user notification would eliminate some issues.
Merged with other ideas, fixed, or declined.
