Tracks have lots of configuration options. You can now copy those settings, including for files, from other tracks for the same conference or one of the tracks from the model conference that was used to create the conference. Usually, this is not necessary since the model conference is already used to create the tracks, but sometimes settings get lost after changes, so this new function provides a way to recover the model settings. (Deadlines are not copied if the model track is from another conference.) The function is accessed using the double-rectangle icon next to the track name:

Chairs and track chairs can now see a flag icon on each paper page. If filled (black), the paper has been flagged, e.g., for messages. If white, it's not. Clicking on the flag toggles between flagged and not flagged.
