Congratulations!
Maybe you should try to create a script which will add new feature for a specific website.
Example: audio alert, collecting data, changing color or background, automated action...
To do so you should use your favorite browser javascript console. You can then turn on your script automatically using greasemonkey/tampermonkey extension.
You should try to create a dynamic website.
And eventually create a web app.
I'm using nw.js for my web app, but you can use electron or Cordova for mobil app.
Now you are free to create anything. The only limit is you.
I have started with a little audio alert on a chat room.
Then finally built my bot for a dice site.
