We need a warning when a shared document is in use.
We use notes to communicate interdepartmentally about events and group reservations. They work really well in that we can enter custom text with no character cap to capture the info we need to share. The problem we're running into is that if one person is editing a note, and another person elsewhere in the building tries to edit it as well, whoever saves their changes first has their changes saved and the other person receives an error message when they hit save and either loses their changes or has to copy and paste into another document and then paste all their changes back in. Ideally two people could work in the same note at once (ala google docs) but even if there were some warning that there was another person editing the note when the second person opens it (like in Word) it would be very helpful to us.
