Hot Node

Hi Nurb2Kea, sorry for the bad experience. Would you like to describe the issues in details? Maybe I can recurring the bug and fix it. My email: Trantor2098@163.com / Trantor2098@gmail.com. For the current 0.4.2 addon version, there is a found bug: Applying Ctrl + Z to the addon will cause some error, I'm not sure if you met it. New version will comming soon to fix that. Btw, blender 4.3 is still in alpha so it's not recommended to use this add-on in 4.3.
