Back to Lunar Nvim
After my problems with Doom NVim, I decided to go back to LunarNVim.
I had never really left, but since both Doom and Lunar are NVim based configurations, they may overwrite the configurations (like from ~/.local/share/nvim/)
So I completely removed both Doom and Lunar and reinstalled.
I also installed ltex LSP for makrdown, which I could not do with Doom Nvim.
My other requirement was projectile equivalent. I found that there is :Telescope projects built-in with Lunar.
