Persistent search results
The search results feeded to a listbox is quite volatile. It would be great if search results could be automatically saved to files. When reactivating such a tab or going back in history it should be reloaded from file. Search results should also be reloaded from files when the program is started (and current tabs display a search result). In addtion commands to save and load a search result explicitely would be great. In addtion search result tabs should have a unique name.
