Hey, thanks for the feedback. Yeah, this is on my todo list. I also wanted to grey out the left part when the comments panel is opened. And another thing I wanted to do as I also said in the article is to replace the substring search with a fuzzy search. I will get to all of these soon.
Feel free to anything else you might want to see implemented. Someone on Reddit suggested me to implement a functionality to follow a thread. This might be a very big feature, so probably going to take a long time to implement this. So, I am not going to get to this follow thread feature anytime soon.
