The :ls command is a great way to see what buffers you currently have open during a vim session. However, if you are trying to find and open a specific buffer it can be tedious to have to find it in the list and then enter a whole different command to move to it (e.g. :b 10).

The bufexplorer plugin gives you quick access to an interactive buffer list. By using <leader>bs and <leader>bv you can open horizontally and vertically split windows, respectively, that allow you to navigate through and open specific buffers from your buffer list. This is a simple plugin you can add to your workflow that can make working with a lot of buffers a bit more efficient.
