bug.n Alternatives
bug.n is described as 'tiling window manager add-on for Microsoft Windows. It is written in the scripting language AutoHotkey' and is a Window Manager in the News & Books category. There are more than 25 alternatives to bug.n for a variety of platforms, including Linux, Windows, BSD, Mac and PortableApps.com. The best alternative is i3, which is both free and Open Source. Other great apps like bug.n are Cairo Shell (Free, Open Source), VirtuaWin (Free, Open Source), Openbox (Free, Open Source) and awesome (Free, Open Source).
- i3 is a dynamic tiling window manager with clean, readable and documented code, featuring extended Xinerama support, usage of libxcb instead of xlib and several improvements over wmii.
- Cairo is a desktop environment for Windows. Its goal is to develop a desktop experience that increases productivity and advances current technology standards.
- Openbox is a highly configurable, next generation window manager with extensive standards support.

NERD tree vs bug.n opinions
I don't like NERD tree as an alternative to bug.n because it's just a vim plugin for browsing file system.
