Re: BTC Trader - opensource live charting and tech-analysis application
I would subscribe to an email newsletter about this app if there was one. I'm very happy about it's development. 
For now I'm working on new version of BTCT -- there would be no new features, bugfixes only.The CPU overheat bug is already fixed and interval changing bug is fixed too.
I'll announce any upcoming stuff on my twitter @bitcoinfreak and this forum thread.
Stay tuned!
