With the new setting turned off:
- No behavioral changes at all
With the new setting turned on:
- When launched from the GUI or CLI without any URLs, dolphin restores session
- When rebooting with Dolphin open, it restores session normally after the system comes back (i.e. no behavioral change here)
- When launched with URLs, Dolphin window is opened showing those URLs instead of restoring session
- When Dolphin is already running and a new window is opened, that new window shows a single tab with the same URL as was visible in the previously-open Dolphin instance (i.e. no behavioral change here)
- "Open Containing folder" functionality in other apps works regardless of whether or not Dolphin is running
