Hello,
We recently changed from using CVS to GIT, previous company I worked we used clearcase.


We do feature development / bug fixing (complex) on branches, trivial changes commit direct on Develop branch.

What I am missing in all the gui tools is the relation on what specific branch did one do a commit.

I searched on the internet and read that there is need to see on which branch a specific commit is done.

From the link below,
https://github.com/pajp/git/compare/master...x-working-branch
I tried this version, but could not see the branches when I started gitk in a git repository, so I looked into his changes, and adapted his code with use of the git commands
git show-branch --all and git show-branch --all --sha1name.
And see the result below:
