It would be great if working on a project sharing project if the Save key command switched automatically to "save and commit".   I know we can do this with workspaces which is workable for the people in the office who get to work all day on the same project. Not as practical if you might be jumping in to ongoing projects for quick dimensions, detail or co-ordination discussions.    Might be a bit more controversial but switching close to close and release could be helpful.
