Vim, tmux and i3 all have similar concepts. You can have multiple things on screen, each can be maximized, and you can also have collections of those things offscreen. This is an over simplification. We're not going to get into things like vim buffers, tmux sessions, and i3 containers. Let's keep it simple.

Nomenclature
Tool	Things on screen	Off screen
vim	windows	tabs
tmux	panes	windows
i3	windows	workspaces

If I'm in i3, I'm usually local to the machine and don't start tmux sessions. So for me it's either ssh+tmux+vim+entr, or i3+vim+entr.

These are the everyday things I have to do in each:

New Vim Window / tmux Pane / i3 Window
Context	Key	Action
vim	C-w,n	New empty window
vim	C-w,s	Duplicate window below
vim	C-w,v	Duplicate window on side
tmux	Prefix,s	New pane below
tmux	Prefix,v	New pane on side
i3	Mod+d or Enter or g	Every app launches into a new window (find mod+g)

Close Window / Pane / Window
Context	Key	Action
vim	C-w,q	Quit this window
vim	C-w,o	Close other windows, leaving only this one.
tmux	exit or C-d	Terminate the shell to close pane
i3		Close the app its normal way

Resize Window / Pane / Window
Context	Key	Action
vim	C-w,=	Make windows equal size
vim	C-w,<>+-	<,> for width; +,- for height
tmux	Prefix,HJKL	Change dimension in that direction
tmux	Prefix,C-arrow	Change dimension in that direction
i3	Mod+r,hjkl	Enter resize mode (or drag bar with mouse)

Maximize Window / Pane / Window
Context	Key	Action
vim	Leader,o	Maximize only this window in new tab (find <leader>o)
tmux	Prefix,z	toggle maximize
i3	Mod+f	maximize window

Navigate Window, Buffer / Pane / Window
Context	Key	Action
vim	C-w,hjkl	Select that window
vim	tab	Next buffer (in this window) (find <Tab>)
tmux	Prefix,hjkl	Select that pane
tmux	Prefix,tab	Next/prev pane, maximized (find Tab)
i3	Mod+hjkl	select that window

Swap Window / Pane / Window
Context	Key	Action
vim	C-w,HJKL	Move window in that direction
tmux	Prefix,{ or }	Swap panes
tmux	Prefix,space	Rotate splits
