If you click Save&Exit an autosave is saved in the Autosave folder, but it would be nice to tell Maniaplanet where to save Validation runs (or replays driven in the Editor in general) in the first place.
I mostly drive and save multiple runs in the Editor to use as GPS or Intro ghosts aswell as the actual Validation run to upload to MX. Having all those files lumped together in the Autosave folder creates a big mess pretty fast. Especially if you have to search through countless pages (I'm at 130 pages already without enabling online Autosaves) before you find the Replay you want to include in the Intro. Please, please let us select folders where to save those runs.
