I am right there with you on every one of these issues. We have been on ASPDNSF since 2008 and I agree that some key functionality is missing with V10.
On the tracking link issue - if you click on 'View Orders' - the link on that page is active and you should be able to easily track from that page. We stumbled on that one.
Also, the email is active from the manage orders page. Just close the Order Detail link and use the email link on the View/Manage orders page.
I have several other issues submitted at this time regarding the 'Send to FedEx' button and PayPal Express. I have also requested patches, but looks like I may have to wait for a future release.
I would be happy to exchange information with other V10 users so we can find fixes and work arounds to some of these issues while we wait for future releases.
P.S. I am NOT a fan of the dashboard on V10 - I miss my Admin home page with daily, MTD, YTD and All Time statistics - basically, the dashboard is useless.
