If you read the release notes on why Lubos combined the old bank tab and cash on hand tab, you will understand that it would not be desireable to have one tab for cash and one for credit cards. Just for the sake of the name of the tab, you lose functionality as described below in Lubos Release Notes. I support having one tab for all transactions to do with money be it banking, credit cards, petty cash, bitcoin etc for the reasons explained in the release notes.
I don’t think that Money is vague because everything is about money - that defines why the word money is actually the best name because it covers everything you can think of from Bitcoin to credit cards and even loans would come under Money. I don’t think Funds would cover loans per se.
Current Accounts in many countries means your main banking account - known as a chequing account in America I believe.
