vmux.vim

Better window management for Vim.

Features

Sane window resize commands mimicking the tmux logic.
Terminal layout management like tmux
Buffer management like tmux
Switch between buffers without caveats -- the buffers are categorized as normal, terminal and other and one category won't interfere with another.
- example: switching buffer with (vmux-buf-next) in NERDTree or help has no effect.
- example: switching buffer in a terminal moves to the next opened terminal, not a normal buffer.
Kill buffers/terminals without interference.
Split window. If splitting a terminal, spawn a new shell.
Automatically setup terminal colors independent of color scheme.
Automatically enter insert mode when entering a terminal buffer.
- If the user previously leaves the terminal buffer in normal mode (i.e. scrolling), it does not start insert mode, and thus preserves scroll position.

Installation
