I got my nerd on for a few hours tonight. I was sick of not to see all the stock market listings on 1 screen on the website, so i made a google chrome extension you can download it here http://www.blott.com.au/assets/gta/gta5.zip
you'll need to Google how to add it to your browser as i'm not going to put it in Google Play. It appears to work for me, id like to know if it works for others. It loads in the datafiles from the website, there is so much data in these files, i can do heaps more functions if it works properly.
