I've just installed Kubuntu 18.04 and when I press Ctrl-Shift-) in konsole, the screen is split in two, but they are the same terminal: what I type in one of them gets typed in the other.
I don't want two views of the same terminal, I want to open a different terminal, just like what you do with terminator.

The workaround, is first to open a new tab, and then use split view. Work in one tab in one view and work in another tab in the other view. They'll be independent. You can use Shift+Tab to switch between tabs.
Using tabs and split view:
And here's a reddit thread on using Yakuake which splits screens the way you want.
