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.
Thats actyally very good point. Our phones x100 or x10K more powerful and complex than computers from 90s, but always works and very-very rarely need reboot.
