"Zoom out" in the branch/merge history
Created originally on Bitbucket by DaveInCaz (David Hollman)
I find it quite hard to follow the overall flow of branches and merges in the visual chart in THG. (Same in command line HG with the -G option). The length of the graph gets in the way.
An improvement would to have an option to to show only the history of branches & merges in the graph - a sort of "zooming out" of the entire history.
In other words, omit all the intervening commits and show only branch & merge points. This would spatially compress the history quite a bit and might make the overall flow of work more apparent.
