@Tamasg So one thing to think about: If people change settings in the NVDA addon, then you release an update, it looks like there settings aren't always updated. And it's really, really easy to break subtle things. If I were you I might consider adding a reset to defaults button in the addon. Because otherwise you're going to get feedback from people who toggled a checkbox like co-articulation without thinking about any of the associated settings and now wonder why everything sounds bad.
