Excellent, thanks for the feedback. The website client is serverless, meaning that once you download it from the ureka server, you don't connect to the server again - so it might be slightly heavier to download initially than other sites - but quicker after that. Yes, getting the right API node is important, so far I'm finding the server detection and selection logic works fine for me.
