I thought about it.
For example, the sidebar page tree supports keyboard navigation.
The UI library I am using, Mantine, follows accessibility best practices and has full keyboard support.
There is still a lot to do in this regard. As the project progresses, more support will come.
In the past, I built a Twitter bot (@threadvoice) to help people listen to Twitter threads in audio format ( https://twitter.com/Philipofficial9/status/11899711858004869... ). I had accessibility as one of my motivations while building it.
