AutoSave
Ever had a browser or computer crash, or closed a window by mistake while typing a blog entry? Or clicked a link by accident, and crossed your fingers while hitting the "back" button just to come back to a blanked-out form? No more!!!
This auto-save plugin for Movable Type acts on all new and unpublished entries, in both the back-end and bookmarklets. Whenever you've typed some new text within a span of time that you define, the entry gets saved automatically! Was the power fuse to blow, simply go back to your entries list to find a recent version of your precious text saved in an "unpublished" state.
