pocket door locks

I'm having a difficult time finding a locking mechanism for the
bathroom pocket door that works and looks good. I really want to find
one that does not require a key (that I will lose in no time). Also, these bad boys can get pretty pricey.

I found these at pocket-door-hardware.com
but I'm not real excited about how clunky they look. I really want to
find something more elegant looking, or far less visually intrusive and obvious. Plus it looks like you have to have a coin or a really fat
thumbnail to lock or unlock the door. I've never used one of these, so
maybe I'm not understanding how they work.

I like how understated these are, but they don't seem very user friendly in terms of initially knowing it's there or what it's for. I'm pretty sure it attaches to (or mortises into) the side of the door that first slides into the pocket and pushes out like a rocker switch to keep the door from closing. This doesn't seem very intuitive, since people are used to having the lock near the handle or pull. right? I don't really want to have to give a training class each time someone new comes to my house and happens to need to use the bathroom. That's no fun. Plus, I'm not convinced of the claim that the strike plate really protects the jamb. It seems a little puny.

I have a couple ideas of things that could be manufactured, but it seems like someone has to have run into this problem before. Surely there is a simple solution that I am missing.

Maybe I'm overthinking this. I tend to do that sometimes.
