Is there a way to hide casts to 0x0 bytes?

[f-raZ0R]

A lot of times, a check for whether a struct exists/isn't empty will be with a cmp or equivalent instruction, against 0.
This will be, intuitively translated as "if struct == 0", or "if struct == null". However, ghidra will still show the cast, making it busily show up as "if struct == (Struct* ) 0x0". Is there a way to get rid of these casts, so the code looks cleaner?

There is an option to use NULL instead. It's somewhere in the decompiler settings.

What's the option called? Can't find it

Thank you!
A bit weird that it uses the color for variables instead of the color for constants, though...
