I've been watching the progress of the new Elite: Dangerous since its kickstarter and although I have access to the Beta, I don't have a windows machine to run it on.
I lieu of this, I've put together the beginings of a trade logging site. It's written in angular and is far from finished but it's taught me a lot.
You can find it at elite.joltbox.co.uk. Sign up and start logging some transactions. Please let me know if there's anything broken. It's probably best to do so in the comments here for now.
If there are any feature requests, bung them in the comments and I'll see if I can fit them in. I have a roadmap of sorts but it's flexible (agile and all that).
