Extra non-investment accounts

[pzbitskiy]

Having Assets:Checking excluded from gains is great but there bunch of different kinds of assets that probably should be excluded as well. Examples are Escrow accounts for rent deposits and mortgage. In the latter example it has constant withdraws and no gain. A similar store with US bank's standard savings accounts with minimal ~0.1% gain.

Maybe there should be an extra sub category for such things in addition to Checking?
