As I get more and more lists I'm finding it hard to find specific lists. A filter and search features needs to be added.

Yep.

I think it could also use more information in the headers of the saved lists.

It could use a way to make notes on a list. I'd also suggest it needs something akin to keeping revisions of the same list so you can more easily see the way you've changed it. That sort of feature would also assist in finding things as you wouldn't necessarily need as many individual lists. A MtG deckbuilder I used had a feature for keeping revisions of a list.
