All categories available for both expenses and incomes
I need to be able to ASSIGN TRANSACTIONS TO BOTH CATEGORIES - INCOMES OR EXPENSES REGARDLESS OF THE SIGN + OR -.
This idea is similar to those:
"Make expense categories visible in income categories"
"Do not treat as a expense / income"
Take a situation like this: i buy tickets for me and my 9 friends. Each ticket is 10$. So my expense is on day1: -100$, but on day 2 I receive 9 incomes each for 10$ = 90$.
Now my budget for movies is waaaaaaaay out of limits, and then on the other hand there are some "other" incomes. The total sum of all my expenses/incomes is correct, but it is not the point.
Another situations - I buy stuff and then I return some of it - again - my expenses stays at the level of the first transactions and there is some otner income that I can't take away from my expense value.
Another example - I borrow someone money, they give it back after 1 day. It summs up to zero, but the transactions are messing up my budget.

You should use outcome with negative sum while reflecting such refund.
Example: I order clothes worth 200€ online and pay them via credit card. Then I return 100€. My expenses state 200€ for clothes although I only kept 100€ because I can't add the other 100€ I get back to the clothes category.
That way my clothes expenses don't reflect my true expenses because I still want to be able to have the same transactions in the app as I have in my bank account.
That would make it so much better!
