Overwrites existing file; doesn't save with new .min extension

[beekat]

I was previously using bistory Minifier in ST2, and it worked fine. In ST3, something is different.

In ST3, Minifier overwrites and saves the existing file in minified form, which means I can't go back and re-edit the original file -- it's gone because it has been minified.

In ST2, I seem to recall that Minifier would save the minified file as a NEW file with .min.js extension (for example). Is this no longer working in ST3? I looked in the user settings for Minifier and I see no options regarding saving the minified file as a new file with a new extension (which ought to be the default, I would think).

Any suggestions?
