I label my trading stalls:

A11

<--

A12

-->

A11 was my first hashed so I changed it to All.  Now, all my C sections are doing the same thing, no matter if I type C 1 or C-1 or C01 or C 01 they all hash until I typ See 1, etc.  They either hash or turn up blank once I'm done typing.

I make trading posts where people can trade with villagers. And use the signs to put locations, it's impossible at this point.
