OK, now I’ve done the same mistake too many times, so I thought it would be nice if it could be avoided somehow. Basically, if you have several projects open at the same time and do some changes in both of them, and then you click you save, you are not getting a message telling you that there are unsaved changes in the other project as well when you quit, which in my case too often has been the projects I intended to save. So basically end up with having to do the things I did all over again as I saved the wrong project.
Hope I explained it well enough
