I applaud this project, “setting all the options”. I think it’s a really good idea to become close friends with the software you use all the time, and getting acquainted through the lens of configuration is one way. Messing around with stuff is good.
I feel it’s worth mentioning that there is a sense in which I think it might be a bad idea. It could be that you’d now be fixating some value that may be optimal right now, rather than benefiting from future improvements to the default settings. But it all depends, of course, on how close friends you plan to be.
"Become close friends with the software you use all the time." That is a beautifully evocative phrase for a lovely idea, thank you for sharing.
If I may share an idea for which I don't have nearly as nice and succinct a summation, but I've come to view my personal computing environments through the lens of being a garden. I spend so much time within them, working, learning, playing and writing. I can see the different seasons of my life reflected through naming conventions, directory structures, scripts I've written and bookmarks I've long ignored. There are new things I want to try and explore in the spring when I hopefully have a bit more free time. I have planted seeds while children slept in my arms or in the next room, and I have enabled their dreams with the fruits of my labour. I would even say I have occasionally communed with the close and holy darkness on long, late nights.
In time everything I have created will return to dust, and probably no one will ever know this garden as I have. But it has still been a place of growth and blessing.
