Every time I open a project, active layers in all layouts are reset to the topmost layer. Very often it's a global layer like HUD or FADE, which is locked and invisible to prevent accidental changes to it.
However if I forget to check which layer is active and try to add/place/paste an object to the layout, it's always added to that locked/invisible layer.
I can't tell you how many times I make this mistake daily, and it's very frustrating.
Could you please make the editor to remember the last active layer in each layout and restore it automatically?
And please add a warning dialogue when trying to place any object on a locked or invisible layer.
