Let's add some intelligence to attachment processing. The way Notes handles attachments hasn't changed in 20 years. It might have been ahead of its time back then, but it needs updating now.
When double-clicking an attachment, the client should automatically either open or edit the attachment based on the state of the document I'm viewing. If the document is in Read mode, just open the attachment. If the document is in Edit mode -- Edit the attachment. When I click on Save in the application that opened the attachment, save it right back to the Notes document.
The 'View' option, im my opinion, is no longer relevant. File viewers inside of Notes are out of date and don't handle document formatting appropriately.
Leave the Save option on the right-click menu.
