I think there really needs to be improved food items that can give perks/heal/restore hunger in a mod. The current food items I see today aren't that good. The models for them are very small and it is just very odd looking.
What I would like to see is something that fits the style of Blockland and people would actually think the items look really cool and people use them often.
I would make this add-on myself, only if I had the DTS exporter for Blender.
