--- Annoyances in Neovim environment:
--- 1. codelldb doesn't terminate C++ program after debugging.    : Don't know how to fix, have asked for help.
--- 2. Sometimes very seldomly the cursor stops rendering, the only fix I found is to restart Neovim.
--- 3. Remove usage of dap-go, dap-python, and rustaceanvim. These are really just providing DAP/LSP configs which I prefer to have without plugin bloat. However, they require more to setup than your average conf.
