Allow exporting scores without invisible items.
I've been working with blind musicians the past couple of months to make scores they can transfer to Braille. One problem with this is that invisible items are transferred to Braille and there is no easy way to skip them without going through either the XML or score and removing all invisible items. There are currently options to omit system and page breaks. It would be a big help to blind users to be able to omit non-visible items as well. This will make a lot of scores that are currently on MuseScore.com easier for them, and make it easier to create a score that is both easy for the blind to use and has proper playback created using invisible items.
I know accessibility is a priority to many of the contributors and I hope this feature will be made an appropriate priority so it will end up in one of the next few updates.
