Over the years of using Vim both professionally and for my own uses, I've learned to just install LunarVim and only add a handful of packages/overrides. Otherwise I just waste too much time tinkering and not doing the things I need to.

I usually keep most of the config. I just move them around to make it more comprehensive. The only time I made a huge change during a rewrite was when I learnt about treesitter textobjects.
