git branch manager ui?

Is there any git UI for managing just git branches, hidding commits? All currently available git clients show big log report开发者_StackOverflow中文版 with all commits in branches, so I might lost the focus of a branch that is not on screen, due to many commits that happened recently.

I want to be able to 'minimize' or to 'collapse' all commits into single dot (bigger dot - more commits are collapsed) or line (thicker line - more commits) and to visualize only branches that then can be manipulated. So, again, it is like SmartGit log view, but with collapsed commits of branch, so I can quickly see just the git branch tree.

There's a nice option that you can use with gitk called --simplify-by-decoration which only displays commits that are pointed to by branches or tags. I've given a "before and after" example below. Any tool that takes options understood by git rev-list such as git log, gitk and many others can take this parameter.

Before

gitk --all

After

gitk --all --simplify-by-decoration
