The way Jira manages unsaved changes is great because it seems to be resilient against any type of crash.  However, when multitasking it is very easy to leave an unsaved change to a description (quite risky in collaboration) or a comment (much less risky).  An old unsaved change which is applied may overwrite weeks of other changes (and a necessary sort through history).

I need the ability with JQL to see all of my outstanding comment and/or description changes (title changes?–I didn't want to test but probably not frequent).  These obviously exist in a database, I need to be able to find mine without viewing every single issue I've touched.
