Keyboard shortcuts and navigation

I am warming up to Postbox, and as I do, I am trying to learn how to efficiently navigate through tasks and views. I think Postbox has tremendous potential, and I hope to see you realize it.

I have a few related questions that I am going to shoot below.

1) After I click on Attachments or Images and I return to the main view, the message list (top portion) of the window defaults to the top. I am currently previewing a message greater than 1000 down into the inbox, however. Right now, I can spend a few clicks going to Go>Next Message and then clicking up back to my current.
I'm looking for a iTunes-like Cmd-L that goes to the current message and/or a default to show the previewed message highlighted with the message list.

2) What's the most efficient way to save a photo to the folder designated for mail attachments? The best I've figured out is right-click save-as from the main view, or Images>Save from the images view. I am looking for 1-click to save from the main view, or your alternate advice.

3) Can photos be rotated in Postbox?

4) Is there any plan to possibly integrate and/or work with Xoopit?

5) Is there a way to view/edit how attachments are handled via Settings? I am wondering if Postbox tries to download all my gmail attachments over imap. In Mail, I learned to leave attachments on the server to keep my Mail working better. See screengrab of Mail pref displaying this item.

6) Please consider making Accounts settings available via Postbox>Preferences (like Mail).
