I have been thinking for some time that why not join forces? In KDE there are several similar applications like Konsole and Yakuake, or KWrite and Kate. Each application has its advantages. The best thing about Yakuake is that it opens by swiping from the top of the desktop with a keyboard shortcut. As for Konsole is great its great customization, being able to configure almost everything and the icing on the cake are its add-ons: its SSH panel and commands. If the idea is not liked, maybe Konsole features could be integrated into Yakuake and vice versa, although I think having a single application would save future maintenance efforts.
Please note that: - kate and kwrite have always shared most of the code, which was really provided by an underlying library (KTextEditor), with kwrite being a tiny wrapper around that library. In the end, since the version shipped with Gear 22.08, kwrite is in fact a reduced version of kate: https://kate-editor.org/post/2022/2022-03-31-kate-ate-kwrite/ - yakuake is a wrapper around the core component provided by konsole, as its description explains: "A drop-down terminal emulator based on KDE Konsole technology". What you ask is already the current reality, and it has been for a while.
