Each time an issues is updated, mantis shows the "Operation successful." page and redirects after a while to the issue page.
This somehow takes a lot of time and is of quite little information, as nearly all operations are successful. So, I feel that this slows down my workflow too much.

I'd recommend either to be able to configure mantis to

• not show the "Operation successful." at all, only show an error page if there was an error or
• include the "Operation successful." message at the top of the follow-up page (this is what bugzilla is doing) or
• keep the current behaviour.

This should be controllable for pages with a single follow-up page only. Pages where the user can select either to go to the issue list or to report the next issue or to view the issue details of the updated issue, this behaviour should be kept (or be made configurable separately).
