SimSettingsManager is a new tool that has been released over on the simMarket store that allows you to monitor and manage your Flight Simulator settings. It allows you an overview of your simulator, and also to compare and rollback all changes that were made in your flight simulator. When new aircraft, scenery or other add-ons were installed or when any FS related files are modified or deleted, it saves a backup of which you can rollback to at any time. In addition to that it also offers frame rate monitoring on each flight simulator execution. Certainly Looks Interesting!
