Would be nice for JIRA to add a "confirmation check" (are you sure) when user clicks on "Cancel" instead of "Create" when doing a story/bug/waste. Currently it does happen that a user fills in a bug/adds a comment to an exisiting one with long description, attachments etc and then misclicks by hitting "Cancel" instead "Create" and all's removed at once. So either moving the "Create" and "Cancel" further apart from each other, a "confirm action" check for "Cancel" button or recovery option would be nice here.
