Our intention was to keep it as simple as possible and though providing some useful functionality.

IMHO technically impossible.

Are you referring to SmartGit 7.1 or 8? Yes, there is a reason why not all Hg versions are supported: there are incompatible changes in Hg, so required SmartGit extensions have to be version-specific.

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.
