Accessibility issues for MacOS 10.15 upwards
Running VoiceOver within MacOS 10.15.7 as test base. Software version MuseScore 3.5.2 which replaces the 3.5 as a new installation.
Issue concerns being able to interact with page in order to read contents of page using VoiceOver cursor.. VoiceOver will announce initial detail only but will not allow interaction with the actual page in order to navigate or edit the page.
The UI itself is ideal with VoiceOver, although it should be that VoiceOver can split from menus, etc and at the moment, navigation to the page means moving from toolbars and menus to the page. so the elements need to be split and created as navigatable object packs, so to speak, so as an example, you can interact with a menu bar, stop interacting with a menu bar, cursor to find a toolbar group, you can interact with and stop interacting with, this doesn't happen.
I really am pleased with the positive movements of making musescore compatible with screen readers.
One of the critical components here, besides the actual score page accessibility and navigation with VoiceOver, is the support for music braille output, whether to display or export to an embosser software. If there's anyone with this experience, please get involved in this, it would be a huge move forward.
