A simple _minify folder question

No. This is registered as a virtual permalink structure, and minified assets are kept in the options table.

The plugin has lost development steam and is lagging behind in several key aspects. I would not use it as a current minification solution.

The best thing to do is to find a host that supports HTTP/2 and not worry about minification at all.

ok.
But this seems like a good solution to matching dependencies…

Is there way to add a turn off button for each object of files? I see that we can view, purge, expire… but can we mute, disable?

Can this be added to code?

I’m not sure what “matching dependencies” means.

For code changes – at this point it’s unlikely the code will be touched again, at least for a long time, if ever. The problem it solves was solved in a better way (read: HTTP/2), hence nobody has any further time or motivation to do anything here.
