I realised I had the habit of searching on the Japanese SE for questions relating the grammar point I was studying, I quite often come across interesting questions, particularly those asking ‘what is the difference between x and y?’ which help me understand the grammar I’m learning at that point.
I decided to make a small userscript that will take the current grammar item, and creates a button that will search the Japanese SE website for questions/answers. 
It’s not perfect, it could be written better and the button could be in a more useful place but it works for now.

After searching, you may wish to adjust or add more search queries to adjust the results. Feel free to adapt it as you like.
