Yeah, orca isn't too bad tbh; it's just not really great.

It's better than, say, VoiceOver for iOS but that's not exactly a high bar.

On top of that, Chromium and derivatives (including Electron) have really flaky support for the necessary accessibility APIs. You're pretty much limited to GTK, Qt, and Firefox or WebKit2GTK for a good experience.

You know, I used to be on the "webshit bad" train and I still kind of am, but Qt is literally the only alternative to webapps when it comes to making cross-platform internationalized GUIs with good accessibility. Hopefully Odilia's addon and scripting support could improve that situation.
