Latest tmux update brings some really nice improvements. Especially the option to zoom a pane which is something i use a lot in vim, also resizing panes will now reflow the text inside them.

From tmux man page

With -Z, the active pane is toggled between zoomed (occupying the whole of the window) and unzoomed (its normal position in the layout)
