Look very good, but the main problem is purple column is too wide.
BTW, my screen is a little small, 1366x768, so something might fall off the screen.
Also, there is a little bug here.
Also, it would be nice if the list here could be updated: The New And Improved List Of API and Third Party Apps
Many of the user scripts aren’t included in here, including Item Marker and Add Context Sentence.
It would be nice if I could create a Userscript and Userstyle myself, but I know very little about JavaScript, and know nothing about JSON.
