Yup. Command-line, git and a dumb text file editor are all that I use.
But I wasn't always this way. Used to be a Windows guy in the past and used to prefer specialized GUI tools over command-line or general tools. Have tried all kinds of planning tools - GTD tools, Trello, some Kanban stuff, multiple Mind mapping tools. All of them had some minor deficiency or the other which I'd end up obsessing over, instead of doing my actual freaking work. It's taken me years to satisfy myself that git and an editor are more than enough.
