Unfortunately on Windows we don't have too much choices when it comes to tiling windows managers. Actually we don't really have a choice at all. The only one which supports multiple monitors, multiple spaces and can be reasonably tweaked is bug.n I've been using dwm on Linux and bug.n comes pretty close functionality wise. Few advices if you want to try it :
- although the compiled version is available run the source directly (it's written in Authotkey). This is better because you can tweak it more and also because the compiled version is registering some hotkeys which interfere with the Windows 8 system hotkeys.Also if you're running a x64 OS make sure you install the 32bit version of Autohotkey otherwise bug.n won't run properly.
- edit config.ahk to configure it properly.
