Income/Expenses should depend on Category

[Maxim Kizub]

You have 2 types of Categories - for Income and for Expense.
I expected that (in 'add transaction' dialog) when I choose a category, the transaction will be categorised to Income or Expense (the plus/minus toggle button did not take my attension), and I was very confused to not see my transactions as expenses.

I propose these options:

a) move the field 'Category' before 'Amount', so users first select the category (and thus - expenses/income status of the transaction) before entering the amount;
b) if the Category was selected - show income/expense status near amount field _and_disable_ +/- button (that toggles income/expense classification of transaction); otherwice (if category was not selected) - keep plus/minus button enabled.

or

a) change +/- button to be (view) as income/expense;
b) depending on income/expense toggle button show only incode or only expense categories in category list;
c) cleanup category on income/expense toggle;
