There are many discussions about pending transactions so I don't know if this has been suggested before or if there are any similar Ideas that can be up-voted:
The current values for the Cleared Status field are "Cleared" (blue checkmark), "Reconciled" (green checkmark), or "Neither reconciled nor cleared" (no checkmark). Add a new value for "Pending" (red? checkmark or question mark).
From what I've seen in the discussions, some institutions include pending transactions in their downloads — if these transactions can be distinguished, simply set their Cleared Status to Pending.
Other institutions do not include pending transactions in their downloads, but they do include the pending transaction amounts in the account's online balance amount. Even though they are pending from the bank's perspective and not downloading, I usually have already these transactions entered into my Q register, either added manually or as scheduled transactions. In either case, I would happily manually set the Cleared Status to Pending. And then when they eventually downloaded from the bank, Q can override the transaction's Cleared Status to Cleared or Reconciled as appropriate.
My bank is one of the latter institutions, which is why my account only reconciles when it has no pending transactions. I've asked the bank to change (or correct, in my opinion) their download, but I doubt that that will happen. Below is my prior discussion about this topic but I don't think it's worth reading; I only include it for reference.
