PROPERTY_USAGE_GROUP = 128
#Used to group properties together in the editor.

PROPERTY_USAGE_CATEGORY = 256
# Used to categorize properties together in the editor.

PROPERTY_HINT_EXP_EASING = 4
# Hints that a float property should be edited via an exponential easing function. The hint string can include "attenuation" to flip the curve horizontally and/or "inout" to also include in/out easing.

# I can find these hints in the property list when I do
print(get_property_list())
# It makes sense, this is just how Godot saves all these properties on the lower level, and they look like they're done right for my custom container node. I just wonder if there's any way to group these properties by adjusting the return value of the property list?
# Do I need to try adding more export hints other than just...
