I have a few suggestions, if they haven't been suggested before:
- Other hack-only items (Pots, Moth Orcid, etc)
- Other Shop-Edit (Namely Ables.. perhaps City stuff eventually too though?)
- Auto-Upgrade (Being able to select to auto-have Nookingtons or final house)
- Insert Structure (Perhaps adding a lighthouse manually, but I can see issues with this like in ACWW)
- Edit Museum (It'd be nice to pick what stuff is in? Maybe?)

Might have more later.
