I'm not familiar with Dark Reader, but I'm guessing it's along the same lines. I've used it with Firefox Mobile for a couple months and have been happy with it.
The new release is working on my Mac whereas yesterday's didn't. Thank you!
I was intrigued by the metadata handling for works; would it be possible to support searching via that data? For instance, I'd be interested in seeing works conducted by Bernstein, or performances by a specific orchestra.
