It's not that big of a deal, but I often have to switch around the order of elements in a list like:
:foo, :bar, :baz
So that the list is now:
:bar, :foo, :baz
It's a bit of a hassle to select one element, move it back or forward in the list and then place it back in the list. Instead, I've written this plugin to do this for you.
In the original case, you would visually select :foo, :bar and type <leader>a,
and the the two elements are swapped around.
