AFAIK investment companies have two accounts i.e. first for stocks and second for money. Money account in my case is probably some kind of technical account and is identified by less numbers than normal account. I see this account number and how much cash is there but I cannot make any operation there, because all is done automatically by my brokerage.
Summing it up, I think current implementation with two separate accounts is correct although I don't see clearly any separate brokerage account in my case.

Different companies do it different ways.  In my case (Merrill Lynch) it really is a single account for both securities and cash.  

I suppose it would be best to allow either method, which makes the change a bit more involved.  When creating an investment account, you get to choose whether cash goes into the same account or a separate brokerage account.  Perhaps the internals are that the brokerage account points to the same account instead of a different one.  The only danger there would be if the brokerage account were separate (as the current situation) then it should not be possible to accidentally put cash in the investment account.

I think you're mixing up stuff.
You cannot count apples (e.g. dollars) and peanuts (e.g. facebook stock) in one and the same account.
I think separate accounts for counting one and the another is the only way.
How do you think logic of your desired account should look like?

As investment companies around the world do this differently, it should not be mandatory in kmm to create a separate account for cash. Here in Canada, the brokerage accounts offered by all the major banks (TD, Scotia Bank, RBC, CIBC and BMO) have cash and securities in a single trading account.

Cash and Securities would not be in the same account. Cash would be held in the Investment account and Securities would continue to be held in the sub-accounts. Buying shares depletes the cash balance in the parent Investment account and selling shares increases the cash balance in the parent Investment account.

The devil is in the details but there does not appear to be anything in the MyMoney model that would prevent this. Perhaps I am missing something?

As Mark said - the cash is in the main investment account and the securities are in the sub-accounts.  The total value of the account would be the current value (shares times price for each security, plus the cash.  Any cash which currently moves to or from the brokerage account just comes from the investment account itself.  It might even be reasonable for KMM to keep two separate accounts internally - the main issue is that the current forced requirement for a separate brokerage account doesn't match how many folks think of their investment accounts, and how some investment firms present the account in terms of statements and balances.

There are several discussions which have gone on regarding changes and enhancements to investment accounts - and although none of this is likely to be touched until after the dust settles on the migration to Frameworks, there will be many inter-related issues to be discussed and addressed.

My Fidelity account holds both the Cash ans Mutual fund investments, same account.  Requiring a separate KMyMoney account clouds things on this side.

This is a known issue, and is on the list for changing,  but it wont be soon.  All current developer effort is going towards completing the migration to KDE Frameworks.  After that, the developers will review all the outstanding issues (both bugs and wishlist) to prioritize the next phase of development.  There has been some discussion about a major revision of the entire way KMM handles investments, so at least some of that is likely to happen, but there is no timetable yet.
