I suppose you may want to try "smartbox: Smart Searching" which is another extension I've written out. Currently, it only works on Chrome based web browsers, I'm trying to bring it to Firefox (I've tried so many times...).
Here is the demo video: youtu.be/1yYbrPPGt6k
You can also find it's source code here: github.com/atahabaki/chrome-smartbox
And Thanks for reply :D
