nvim-buildme VS vim-buftabline

For 2. I've developed a very small plugin that might suit your case: nvim-buildme. Basically you create a shell script at the root of your project which contains your compiling/static analysis commands and the plugin simply takes care of executing that script in a Neovim shell in the background and notifies you when it's done.

I use buftabline and treat them like tabs in a graphical editor.

You’re right, I essentially built my own plugin. And I know could use a plugin like vim-buftabline or vim-buffet to accomplish a similar look.

ap/vim-buftabline for buffer line

You can see your buffer list with :ls, :b (note the space), or with a plugin like vim-buftabline (ap/vim-buftabline: Forget Vim tabs – now you can have buffer tabs)

this and ctrl+p with https://github.com/ap/vim-buftabline

ap/vim-buftabline can display the buffer number which you can use in :bN commands, no idea if it works in neovim. But I most often use tab completion in a :b command.

It's also not a (super) new idea – my plugin is just a Lua ripoff of [vim-buftabline](https://github.com/ap/vim-buftabline), which had its first commit in 2014, and I think Airline may have had it before then.

I like to use Buftabline https://github.com/ap/vim-buftabline and set the next/prev tab to /

In this plugin wishlist thread, I mentioned how I'd like to see an implementation of vim-buftabline in Lua. -olivier directed me to his plugin, nvim-bufbar, and encouraged me to use it as a base.
