Is your feature request related to a problem? Please describe.
Currently we have a widget that shows net income and net expense for the selected accounts. I need a similar widget which can show net cash in and cash out for the selected accounts which includes transfers. This will be very useful information for getting better idea on the expense when required.
Let's say I have three accounts A, B, C. Each have 1000 USD initially.

I transfer 100 from A to B.
Considering all 3 accounts net cash in and net cash out are 0.
But considering B and C. Net cash in is 100.
Considering A and C. Net cash in is 0 but cash out is 100.

This is useful when I have big amount in savings account and transfer an amount monthly expenses to a spending account. Technically it's not income but it's an amount which I want to see when I use that spending account for monthly expense.

It'll be great if this option is enabled in the transaction page top bar which shows monthly spending summary. We can choose if we want to see income/expense which is current feature or cash in cash out.
