One feature I need (and would like to tinker with the code to add it) is support for subtitles in multiple languages at the same time. http://voicetube.com does this to help people learn English; I'm trying to learn Chinese.
Unfortunately life in Taiwan has been really hard for the last few months though, so I'm preparing to leave. Busy looking for new jobs in other countries now.
What kind of job are you looking for?
I'm most passionate about control systems/automation, network admin, and circuit design. But I've done a wide variety of other projects (big data, web apps, device drivers, tech support and repairs for friends). I'm not good at art or marketing, so front-end design isn't for me. I'll consider pretty much anything else though.
Learned english when I was a kid by watching cartoons with subtitles... Good luck.
