Support for Google Fonts
Include support for Google Fonts as text font option.
Like Bravura, Google Fonts are available under SIL Open Font License.
Support for Google Fonts would significantly and immediately improve the options for user text font selection, it would create a definitive and limited set that would be compatible with publishing scores to Musescore.com with consistent text font rendering.
Might be worth exploring enabling a font manager (similar to how Adobe manages fonts) that would only install the necessary fonts required for a specific score when needed, or to enable download/installation of new fonts via the Resource Manager.
