you can use
set nojoinspaces

Normally when I want to tidy up a paragraph I run in normal mode:

gwap

gw{motion}  Format the lines that {motion} moves over.  Similar to |gq| but puts the cursor back at the same position in the text.  However, 'formatprg' and 'formatexpr' are not used.

For those of you who use firefox and normally add "tags" to make easy getting back to some interesting articles I recommend reading:
https://superuser.com/questions/414369/how-do-i-change-priority-of-firefox-address-bar-suggestions-to-tags/414387#414387

Now every time I want to see my tags "nvim" on the firefox bookmarks I just type:   + nvim

nnoremap <silent> <leader>x :bd!<cr>

Close other buffers (keep just the current one opened)

   function! CloseAllBuffersButCurrent()
       let curr = bufnr("%")
       let last = bufnr("$")
       if curr > 1    | silent! execute "1,".(curr-1)."bd"     | endif
       if curr < last | silent! execute (curr+1).",".last."bd" | endif
       echom "All other buffers unloaded!"
   endfunction
endif
command! -nargs=0 Bonly :call CloseAllBuffersButCurrent()
