I think a "never break follow" toggle would be nice. Also, an additional follow-type command the brings toons to the exact same spot you are standing on.

A loot auto trade type /script or something would be awesome too. Main loots and automatically hands it to a group member in a single command without opening windows.

Reduce the guild charter to five people OR ten toons regardless of what account they come from.

Pooled/shared money. Perhaps have a guild account and you can toggle if your toon uses that account or not. Maybe they already have this, never ran a guild before.

Running multiple toons from the same account!!! I wish!!
