There is support for linking to JIRA issues in SourceTree. Many thanks.

But I still need the discipline to type the issue reference in every new commit message. Being able to select a previous commit message helps, but it would be nice if we could somehow define that, for the time being, `SRCT-5345` and `SRCT-3534` are the issues that I am working on, and that they are added to the first line of the commit log automatically ... or something.

(We tend to use the format:

SRCT-5345: added links to the other side

It turned out that we are not alone. In this commit we added links to the other side in a first version. This is rather a POC, than finished. Will be refined in later commits.
