Three expectations

Hi everybody! MuseScore is really fantastic, professional tool. Good job! At this moment I see three major problems:

1. It would be nice to have possibility to change simultaneously duration of all selected notes by one click. It will be useful to change articulation fast and easy (see the example below).

2. The "Instrument text" is very smart tool. For example, it gives possibility to change sound articulation if using properly prepared soundfonts. But... each time you insert instrument text, MS creates new track in the mixer section, even if the text is copied from one place to another. I think, that identic text (this same instrument change) should be linked with only one mixer track.

3. Support for installed in system hardware and software MIDI OUTs - not thru "JACK Audio Server which is a bit complicated (especially for Windows users).
