Remove players from Full Score

I have import an Music XML with contains a score for fanfare. This XML include parts for add instruments like Trombone in Bb, Tuba in C etc. I will exclude them from the Full Score.
There are 2 options:

Option 1:

  • click in Layouts on Full Score and click at the left in the players list. This works but is very slow!!

Option 2:

Option 1 is the correct way to do it, and it is indeed very slow in the current build (because, as Paul has said elsewhere, we emphasise correctness over speed to try to ensure that we don’t get any hard to reproduce bugs), but this is one of the things we have been working on since the initial release and you will find it much faster in the first update.
