I usually use about 5 konsole tabs open at the same time.
I'd like konsole to remember it's state on exit and restore it on start.
That includes:
 * open tabs
 * working dirs in open tabs
 * window location and size (assuming it fits current screen)

In KDE4, konsole saved state on logout and restored in on login.
In KDE5, konsole starts with 1 tab and doesn't remember size and location.
