"Clap buffers" should be ordered in LRU-order

[sscherfke]

The list displayed by :Clap buffers is currently sorted by buffer number. It would be more convenient if it was sorted descencingly by the time of last use.

I have mapped :Clap buffers to <leader>ob (open buffer). If the list was sorted by LRU, I could simply type ,ob<CR> to toggle between the both last used buffers (e.g., implementation and corresponding tests).

An option would be nice and feel free to open up a PR, all you need to tweak is s:buffers:

vim-clap/autoload/clap/provider/buffers.vim

Lines 8 to 14 in a29c79e

	function! s:buffers() abort
	redir => l:buffers
	silent buffers
	redir END
	let s:buffers_cache = split(l:buffers, "\n")
	return s:buffers_cache
	endfunction

The possible related api: :h getftime().

Thank you for that fix! :-)

It would be nice, if the current buffer was omitted from the list (or at least, put at its end). Currently, you have to type an additioanl Ctrl+j (or down) to move to the second entry when you want to toggle between buffers.

Makes some sense. Please create a new issue for that feature.
