Generic filter vs. Regex + API Documentation

[scott113341]

"Case-insensitive regex filter" is esoteric. We should consider changing this in name and functionality to a generic filter like in such as String.prototype.indexOf.

We can still retain the full-blown regexString functionality in the API, but not include it in the UI, except for a link to full documentation of the API. This way we can also document the minDuration.

I think minDuration is worth surfacing in the UI, just hidden. #7 (comment)

Good idea on surfacing the API docs
