Track one-to-one emails, but not clicks

[Shlub]

The Marketing -> Emails settings has the option to separately activate email open tracking, click tracking, or both.

For one-to-one tracking, there is only one activation button to track both emails and clicks.

This was discussed in this post.

I would like to know if my emails have been opened but I find it embarassing to send these sidekickopenxx.com links to my leads.

So it would be nice to be able to activate email tracking and click tracking separately.

It would also be nice to be able to activate these on a per-email basis in Conversations. This is already an option in the chrome extension.
