Build planner is too laggy

Hi,
Could you please consider increasing refresh rate of editor's UI?
It is too sluggish and makes harder to hit the right spot when clicking.
I assume it's done this way to save some resources for simulation,
but at this point it reppels me from creating complicated and congested
pipe/conveyor system. It's a real pain. My CPU and GPU are used in 50%.
I'd love to have an option to increase refresh rate of build planner's UI.
Pretty please.

This is common in games made with the Unity game engine. If the Developer does not have access to the Unity source code it might be impossible to fix.
