This looks like a great mod, and a replacement for Living Economy, which means I'd be able to cross replacing Living Economy off my to-do list.

One thing, though...
- Salaries
Weekly Salaries from the Mage's and Fighter's Guilds (the two 'legitimiate' Guilds); Salaries are equivelant to 200 * Rank. If the Player has a Bank Account, the Money is paid in directly; if not, it magically appears on their person.
- Imperial Pension
Those who have saved Cyrodiil from Mehrunes Dagon gain the Imperial Pension of 500Septims a week, paid in the same manner as Salaries.
- Land Tax
A Tax on each home owned by the Player.
- Horse Tax
Cost of looking after horses.
These should be a different mod, or at the very least be 100% disable-able. Controlling merchant resources is one application, controlling player income is another; there are multiple alternate solutions to the latter, and this is one of those situations where flavor is more important than mechanics to many.
EDIT: Ditto on the mercantile-perk salaries. That should never have been in LE to begin with.
EDIT 2: Oh, I see, this is going to
include the bank... hrm. Does the bank note mechanic directly interact with your other scripts? If not, there's no reason to have the two in the same ESP. If so, I wonder if the bank notes could be put in a mutual-dependent ESM, so that merchants and banks can both use them, but each is independent of the other?
