Attachments in bank reconciliation are a dog's breakfast

This is a comment I posted in reply to another thread, but I felt that it would be better as its own topic.

The ability to include bank statements with reconciliations now appears to be available (in fact, it downloads the statements from the bank, which I didn't expect), but it's incredibly buggy. I have attached what I see when I click on "View statements" in the "Reconcile" tab. There are several problems.

1. Although the top of the screen shows that I'm working in my "Chequing - CAD" account, absolutely all of the statements are for my "Chequing - USD" account. If I switch to any account that has statements, only "Chequing - USD" statements are shown in the "Reconciled" tab and none in the "Unreconciled" tab.
2. If I switch to an account that doesn't support statement download, I get a message saying so, but the "Unreconciled" tab shows statements for my "MasterCard" account and the "Reconciled" tab shows nothing.
3. As you can see from the list, many statements have been downloaded twice.
4. Furthermore, all these statements were downloaded on December 2. At that time, my November statement was available online, but it's not in the list.
5. When I select "History by account", I can see the statements for the right accounts, but the "duplicates" problem still exists and the end of November statements are still missing.
6. The statements that have been downloaded don't show up in the global "Attachments" list.
7. The statement files are named according to the name the bank gives them. I have a naming convention I use and I'm unable to rename the files to something more sensible.
8. Although there's an "Attach" option for older reconciliation reports, because there's no connection to the global "Attachments" list, I can't link to the statements that I have stored there. If I want to attach older statements, I would have to download them from the global list and re-upload them here.
9. Although the history is supposed to show "Attachments" for reconciliations that have attachments and "Attach" for reconciliations that don't, I can in fact click on quite a few with "Attach" and find that they in fact do have attachments.
