We agree and hence have already built it into version 8.

Often there is no single Git command but rather multiple Git commands executed in a row or different Git commands executed depending on the deleted option(s).

This currently only works from the "Journal" (former known as "Outgoing") view.

The "Format Patch" default external tool already should provide the ability to create patches.

In the first case, develop tracks origin/develop, in the second one it doesn't. How this can be improved in SmartGit?

If you already have to edit the code, why not use copy-paste now to get the achieved effect?
