Thank you for your support! I have indeed put a lot of thought into it, and it's something I use often myself. The crashing with large data volumes is a known issue that many have feedbacked on. I have plans to optimize it, but I'm not overflowing with good ideas. If anyone could offer some suggestions, I would be immensely grateful!

What's causing it to crash, the left panel or the right?

Are you using CodeMirror for the left panel?

The issue isn't with the editor itself, but rather because rendering becomes very time-consuming when there are too many DOM nodes. This is due to the specification limiting to only one main UI thread.
