I'm aware that extraSprites: has a maximum value and that it can be increased via reservedSpace: in the metadata.yml file.
My understanding is that increasing reservedSpace: also increases the amount of RAM required by the computer running the mod as it reserves the space the potential images will need, so unnecessary expansion is discouraged.
Does the listOrder: variable have any similar limits?
If possible I want to leave large unused spaces in the listOrder: sequence between groups of items so that future expansion can be done without much reorganizing.
