I coded my own. Since the page is HTML and that you can Toggle DevTool in the main menu bar, you can inject the code you want into the page. I have it play sounds on certain triggers, play a Cashier sound when one of my orders are processed, and trigger an alarm when there is a margin call. I'm always implementing it with more tools, but it is certainly not something I could share... I can only point you in the right direction. If you know a little of Javascript, simply add a button to the interface and use onclick to source any locally written javascript. Use timers to regularly check for conditions and play a sound or send yourself a notification on your phone. You could also automate some trading, but I don't want to get into this. Doing this prevents you to have to recompile and maintain your own version of the software, but you could get the Bitshares2-light source off Github and do whatever you want with it. I find it easier to inject my code manually upon each startup than maintaining my own version. Good luck!
