On Completion v On Success

[PlateauRealm]

In the Synchronization Settings, when running a command, what is the difference between 'On Completion' and 'On Success' trigger options?

Also, does anyone have a command line and app combo suggestion that can redirect or pipe the result of the sync to a cleaner, stylized message window instead of the ugly black command prompt window?

Maybe the following options would be more clear?
- On success/errors
- On success
- On errors

[PlateauRealm]

Is this a correct assessment of the trigger options then?

On Completion - Sync completed with or without warnings/errors
On Errors - Sync completed or not with warnings/errors
On Success - Sync completed without warnings/errors
