Thank you so much for mod updating! So, here are some minor issues in the new features:
• Unusual control keys like side mouse keys (Button 4, Button 5...) or amesc keys do not work for scroll control. I hope it is possible to fix.
• nbt scrolling not stops after pressing the scroll key (partially fixed by setting a huge scrolling delay)
• carriage return symbol in the end of copied text (useful for json but inconvenient for "mc give nbt")
[Short demo]

If you could be so kind to tell me what system you have (OS + mouse model) I can check if I can borrow something similar from friends

I'm sorry, I don't know how I could have missed this... Windows 10 Home, OKLICK 745 G

Sorry for the long delay in my response, I was pretty busy and I couldn't get to it

I'm sure there's a way to fix those, but I don't have such a mouse so I can't really fix it. If you could be so kind to tell me what system you have (OS + mouse model) I can check if I can borrow something similar from friends.

nbt scrolling not stops after pressing the scroll key (partially fixed by setting a huge scrolling delay)

It actually stops for a few seconds, the intended way for it to work is to press the button that stops the scrolling. I'll check if there's a way to make it feel better without rewriting half of the mod's code

carriage return symbol in the end of copied text (useful for json but inconvenient for "mc give nbt")

I'll fix that in a sec

Scrolling now stops when pressing up/down with commit e593caa

I'm not actually able to reproduce the CR at the end of the copied tooltip. It never shows up for me. Would you mind sharing your mod list?

Oh, it was caused by a Color Uchained mod (removes the restriction on entering technical characters like § into the chat). I forget about it (◔◡◔)
