When you have a lot of things in an updating list, then you go to the variables tab, Scratch will lag out.

Repoduction steps

1. Enable variable manager.
2. Go to the editor.
3. Create a bunch of large lists (500 items each, preferably with decimals) then continuously change each item.
4. Go to the variables tab while the program is running.
5. Watch scratch lag.

Maybe add a "Show More" button to show more.

Actual behavior

ScratchAddons trying to update every single item in the list into the text.

I can't reproduce on my laptop with this script.

The editor does lag a little, but not any more than if I had those monitors shown. I tested on both Chromium and Firefox.
