I understand you point of view, but honestly it will be good to have possibility to quickly check 'commit successor in a graph view from a phone.". I'm working with quite legacy systems (15-20yo) and sometimes, when I have some ideas about resolving some issues it will be good to quickly check backward and forward histories of commits around to verify something..
Thats not a dealbraker at all but it will be nice to have.
Main issue (as mentioned at HN) - no clear licensing or sorting by licensing. Some icons (such as Amazon) are not permitted to use by third parties. HN thread: https://news.ycombinator.com/item?id=36837442
