I'd see an option for running Yakuake as "regular window" (like Konsole) with many instances. Invert case has Tilix terminal application, like here https://github.com/gnunn1/tilix/wiki/Quake-Mode Tilix is a "regular window" application by default. Tilix also allows to run as Quakelike terminal. Yakuake could do opposite. Yakuake is Quakelike terminal Yakuake could also run as "regular window" application. This would solve (partially) the case with Konsole application split (which is not intuitive for someones). Because Yakauke is decent application with embedded Konsole AND has intuitive splits. Would you merge such change if it was happend?
Sorry, no, I have no interest in that. It's better to work on Konsole's split code instead.
