I've been an avid Vim/Neovim user for several years now, but I've never been able to really get into some of those pre-made configurations like LunarVim. I personally only like to add plugins for things I have identified as lacking, but I can see why a pre-made solution would be nice. However, last I looked I found the documentation rather lacking. Even getting a list of what plugins they add, or a general sense of the keybindings they've changed was difficult, not to mention the difficulty if someone was learning Vim for the first time on top of that.
