Actually... I did nothing to the map manipulation, it was exactly like that in the Simplified configuration. In the Simplified version, RB + left-right was mapped to mouse wheel up/down, while RB + up/down was mapped to PgUp/PgDown, allowing for both zooming and layer select.
In fact, now that I think about it, it might be the OPPOSITE; zooming and layer selecting are most likely not working now when clicking R3, since now it moves to another layer where RB clicks, doesn't shift. :/ I'll have to check it in retail, but I'm sure I can fix it somehow.
I updated it a few hours ago, so no, you should download it again. In my opinion, my new "Hold Select" configuration supersedes and makes obsolete all my other configurations, including Simplified.
