It sounds like you think this is a bad thing.
The tab switching is one of the main things that annoy me on a mac, and I'd describe myself as a linux tiling window person first, windows user only second.
Also my mac usage is hopefully only temporary, so why adopt to this - to me - inferior way.
And jftr, I don't plan to use this - I kinda like NPP, but I prefer to use TextAdept on Linux and Mac for notes anyway (and not vim, which is weird, but I guess I am weird with my choices).
