Pantheon Terminal remembers the window size, position, windowed/maximized/fullscreen state, and open tabs in between sessions.

Using the Granite Dynamic Notebook widget (which includes tab close history), double click the tab bar for a new tab, duplicating tabs, quickly closing all other tabs, auto-hiding/revealing tab close buttons, etc.

Cons
Con Heavy
Con limited customization options
Con RAM usage increases considerably over time
There is a RAM leak when using the Pantheon Terminal that adds up over time and use.
Con Incompatible with LTS Ubuntu
Pantheon is developed and binaries are released for a near blessing edge operating system (elementary OS). As such, installing it on an LTS Ubuntu system may be nearly impossible without replacing a large portion of the LTS stack that Ubuntu-targeted software expects.
