I mean just kinda treat them as folders where you have an option like “View Snippets Grouped by Tag” and it then just shows you a list of your tags with a count indicating how many snippets are “in” each tag. With a single snippet being able to be attributed to multiple tags I would recommend not looking at this as a problem and let the same snippet appear when the user clicks either of the tags it is attributed to.
I think this is best because it doesn’t add any new functionality to the backend and is, I think, just a front-end endeavor(?).
By the way, thanks for being so responsive with this. I think this will add real value to those of us who have a bunch of snippets we are working with. What I believe this evolves into, at least for me, is a way to sensibly organize them together because the next most logical step (beyond just being able to manage the snippets more effectively) is to determine which groups of snippets should be isolated (in our thinking) and turned into an actual plugin.
