I really need a bit of feedback or comment about this because IMHO qgit annotate is *almost* very similar to what you would ask, so I need to understand well the difference: FIRST WAY After annotating a file history (double click on a file name in bottom-right window or directly from tree view), you see the whole file annotated. If you have the diff window open you see also the corresponding patch (scrolled to selected file name). Now, double clicking on the chosen code line in file content makes currently two things: - Diff window is updated to show corresponding revision patch, i.e. the last patch that modified that line of code. - File content, as well as file annotation, changes to show the content of the file just after the patch was applied, from there it is normally possible to go back in the history of that code region in the same way, i.e. double clicking on interesting lines. Biggest limitation of 'annotation browsing' is that 'code removing only' patches are not annotated and you need to check them directly in diff window. SECOND WAY Without opening the file viewer it is possible to select a file (or more then one or one directory) from tree view and press magic wand button. This causes main view to be updated with git-rev-list -- <selected paths> content, i.e. a filtered view. With diff viewer window open you can browse across file patch history related to chosen file. Biggest limitation is that all the revisions who touch the file are shown, not only the ones limited to a selected region. IF I HAVE UNDERSTOOD... If I have understood what you would like to see it something like the following: - From diff/file viewer window select a code region. - Press Magic wand button and feed git-rev-list with <selected path> _and_ <selected content> - Show git-rev-list output on main window as usual, but now selected revisions are filtered out not only for path but also for region of code touched.
