When importing a solution or starting a publish all this is shown by a notification "Currently importing ..."

This would also be useful for the deletion of solutions:

• after depooying a new solution version which replaces some older solutions or hotfix solutions, all these outdated solutions should be deleted: ss when starting with the first solution, you*ll have to wait until this deletion is completed until you can continue with the next one. To simplyfy this waiting you now would use a second browser tab to watch the hisotory.
• simple solution deletion - when can the users continue working? Then it would be convinient to get a notification when the deletion has finished.
