Save timeline settings in preferences or with score
Please consider saving (in preference file, or possibly with the score) which lines of the Timeline view were last shown or hidden (e.g. Tempo, Time Signature etc), and the size to which it was last zoomed.
Currently when starting MuseScore, all the lines are visible even if most were hidden by the user during their previous session. It would be useful if the same set of lines were made visible each time.
