Every member of our team can access any particular file for editing and reviewing. It allows a feature to indicate if someone is editing the file so there is not crashing of users. Review collected by and hosted on G2.com.
It would be good if everyone could edit the file at once without crashing, but at least we can know that the file is in use to avoid the crash. It's good to be able to choose how long the file is locked for editing. Review collected by and hosted on G2.com.
