There is a distinction between "doable" and "usable".
I should switch to Terminal every time I want to toggle hidden file visibility?
Or write a service to install on my Finder toolbar. (I did this, because I'm not Joe Sixpack, but it's still annoying. If I wanted to write my own UI, I wouldn't have gone out and bought one.)
Apple has decided that regular users should never see hidden files. I can see how this might be annoying to you, but I don't think I can be convinced that it's a bad justification.
Someone wrote a little app that toggles it, but honestly, if you care that much about it to ask, just leave the hidden files visible all the time. I've found it to be the path of least confusion.
