When you run an operation in Studio, such as the re-index of a translation memory, Studio becomes unusable until the background task on the server has finished running.

As the task is being run on the server, not on the client, and something like the re-index of a large TM can take a considerable amount of time, why not let the user continue to work, and have a notification pop up in the new 'Notifications' pane when it is done (or if any errors occur).

If the user has closed Studio before the task completes, then maybe send them an email when it has finished.

NB: I am aware that you can run these tasks on the GroupShare web UI, but you have to keep checking whether the background task has completed. It would be nice to be able to do this from within Studio, and also to make further use of the 'Notifications' pane.
