I converted my script into a Greasemonkey script (attached), showing the live log on the right of the game window. The result looks like this:
To use it you have to install Firefox with the Greasemonkey plugin and open the attached file with 'File'>'Open File...'
Will it also work on Chrome/Greasemonkey?
I'm not sure about how greasemonkey works on chrome, but I have the script running with chrome right now. Steps:
1. Open Goko_log_prettifier.user.js with a text editor
2. Select all the text and copy it to the clipboard
3. Start a new game on Goko.
4. Press ctrl-shift-j to open the chrome dev console.
5. Paste and press enter
The log might not appear till you've clicked a few cards.
If you'd like to have the logs appear the dev console (no highlighting, but you can undock the window by clicking the left most button on the bottom of the dev window), follow the same steps as before, but copy/paste this instead:
Dom.LogManager.prototype.old_addLog = Dom.LogManager.prototype.addLog;
Dom.LogManager.prototype.addLog = function (opt) {
this.old_addLog(opt);
console.log(opt.text);
};
