Not to fear, it's still around. You can find it in the Edit->Insert menu or in the editor's context menu, as Insert Into Multitrack. Currently, you can use Cmd+Shift+I to insert your current edit view selection into the last session you were working on. There's also an option to insert into a new multitrack session - the key combo for this in not bound. You can redefine both in the keyboard shortcuts dialogs (Edit...Insert Into Session and Edit...Insert Into New Session, respectively). The keyboard shortcuts aren't currently showing up with their menu items, which looks like a bug.
Thanks for the heads up - we working on filling out the keyboard shortcuts, so it's helpful to know what people are missing from past versions.
Can I reply to this email or do I have to ask questions on the forum?
Thanks for getting back to me so quick...I couldn't be more excited!
Looks like you can reply to the email and it ends up on the forum.
I don't think you can put attachments in the email, so if you need to post a screenshot or something, you've got to do it on the website.
