Maybe yes, it's a good idea for a future version.

Thanks for this suggestion. I didn't completely understand the meaning of this value before your post. However I think I've a problem with my accounts. I've imported them from QIF generated by money 2000. the final balance didn't exactly match the balance of the same account in money (about 200€). ...

You can do this by touching the matching transaction in the bottom of the window.

Ok will try to do it.

The reconciled balance is displayed under each account, you just have to mark the transactions as reconciled and check that the reconciled balance is the same as the one on your bank statement.
Perhaps I missed something here ?

Ok I will change that in a future update.

In order to do that you have to use the "Make transfer" button of the window's toolbar. The "Convert as transfer" menu only works with transactions having the same converted amount.

You can create them with the "Advanced…" button, 3rd one in the filter bar.

That's exactly what I was going to say

You can do it, there is a switch for that in the graph settings.
