Dear Maintainer,

The "Not deleted" view is implemented inconsistently in icedove. The "alt"
menu, accessed by "alt-v" should normally give this view under "messages"
but that submenu is not visible initially. The hamburger menu on the right
provides the view->messages->not deleted option, but immediately resets to
"all" after any folder change. Lastly, customizing the toolbar and adding
the view menu there allows "not deleted" to be selected and remain after
changing folders. Preferrably all three of these methods should always be
available and behave identically to the customized tool bar, saving the
setting as the user navigates to different folders. Ideally, a default
view other than "all" could be configured to avoid changing this for each
folder individually, but I suspect that would be an upsteam feature request.

Configuration details:
- Server: remote imap server
- Delete behavior: just mark the message for deletion
