I am searching for a graphical git repository viewer. Gitk is nice and distributed alongside git itself, gitg is a (in my opinion) better alternative to gitk but both have a lack of features (searching for commits/tags/..., switiching/configuring the representation of time(zones) and so on).
As I am doing all git stuff directly in the terminal I do not need some overloaded GUI who tries to do all the magic of git, I just want an efficient viewer for graphical representation of my files, commits, branches, tags and so on with more features than gitk/gitg.
Any suggestions?
Edit: Most times I'm working on linux.
