Choosing a category should dynamically filter results immediately

Otherwise it's two taps - choose a category and then click search.

It took me a few seconds to realise that the results weren't being updated, so it should dynamically filter results ideally. That or having a sidebar or header which allows navigating to the category immediately.

That might be doable with some javascript which would auto-submit the form. Eventually, some AJAX going on might be even cooler.
