since the last release i have now the possibility to lock the class, but its now different to before, where i needed to scroll down at the advanced tab. Now i have this grey field where it doesnt let edit the selector and i need to always select the id to edit it. I would suggest to always make the id in the selector selected or active and not the class, especially when i locked it, because when i locked the class, i intended not to change the properties any more and dont want to get locked out from the selector while the class is selected. Like i have a margin-bottom class, i set it to 1rem margin-bottom and i will never make any changes afterwards. It remains like that.
