A column 'modified at' with datetime on the 'Show changes' list of modified files could allow to sort files. I usually have many modified files on the list because I make sometimes changes and don't commit them before I finish them. In the meantime I find a bug. Fix it in a couple of files, and then I must search the whole list for this files to commit them. When I could sort the list by the modified at column I wouldn't had to search for them. I think You know what I mean. When not I can submit some screenshots or more description. Thanks, Szymon Jeż
What you describe is a workaround for a lack of a special feature "shelve changes".
