Ok so it seems there's certain problem in how webkit works in silica, it tries to intercept elements like popups and lists mapping them to silica-based components, and hence would require separate handling for that to work properly. Trying to figure that out but on each line WebKit scream on me it's highly experimental and I shouldn't use internals Another possible solution would to attempt using browserWindow instead of WebView - the critical part though is an ability to intercept link clicks (to catch pebblejs://close call).

Will check the search, didn't try it yet actually.
Edit: well, the search works to me, but works a bit odd. I.e. I enter apps page, type snowy in the bottom docker, hit search - and it returns me plethora of weather and health apps, but of course not snowy. Also for the search some host with strange name (algloia.io) and hardcoded api key is used. which hints me it's some third-party search engine.
Edit2: oops, sorry, fixed one of those stupid mistakes.
