Coming back from Redcore-linux to FreeBSD as development now i have neovim under control.
What does not work : swift (no language server available for FreeBSD) & F#.
For less known languages zig,nim,odin i have,

For all other languages , coc plugin is very powerfull, you get parameterlists with types when you enter functions.

Here the config,

What does this gives ?
- To the left you see a tree of your directory and files, which you can open.
- On top you have a bar with different files you opened
- There is a fuzzy finder to find files
- On bottom there is a statusline
- To the right there is a scrollbar.
