I added an income reminder, and the only way I can see it is if I open all reminders.
It lets you choose an account, but it does not show in the account in bill reminders and income
I have to add a bill reminder instead, which adds the income as a negative instead of a positive. Then it shows in the account.
Additionally, if you add an income reminder, it only gives an option to add as a deduction on the form, not income (this,I think, is a bug or form description error).
