Thank you, I'm glad you find it useful! The reason I didn't implement auto-parsing in the text editor is that I want it to avoid affecting the tree component on the left side. Sometimes, I like to write something before copying the tree. It's like a scratchpad for me to finalize the text I want. Also, since it's auto-generated, if it were also auto-parsed, it could cause an infinite loop whenever anything is changed.

Drag-and-drop functionality was actually the first thing I considered. However, I want to keep the code clean and avoid involving too many third-party libraries. So, I came up with this method to make reordering easy while keeping it simple to implement.

I will submit it to Superlaunch, although I feel that it might not be valuable enough to be considered a product :)
