Image Resize Dialog
Mailplane 3 doesn't show the resize dialog anymore if the image is below a minimum file size. Go to Mailplane 3 > Preferences... > Attachments to define it.
Copy/Paste to Attach Files
Open Finder, select some files, copy them to the clipboard and paste them into a new message inside Mailplane.
The print dialog does now include page orientation.
