Oh this is very nice and does seem to help quite a bit, though I haven’t tested it exhaustively. I do think it’s a solid improvement.
One suggestion I’d make: If I click a topic, read to the end, then press Back in my browser, is mouse focus kept on the previously-clicked topic? I can tell you right now that my next biggest frustration will be having to navigate back to the topic I clicked into in order to find the next topic. If I click a topic and press Back, could keyboard focus be placed on that topic’s link in the list?
Oh and BTW, there’s some weird control labeled something like “Select % name or value” below the last post in a topic. Is something not correctly escaped? I don’t know the exact value of what was spoken since I’d probably have to copy the phrase directly from NVDA’s speech buffer. It didn’t appear in the page text itself.
