Kirigami supports custom ContextDrawer and this was really helpful for implementing NeoChat fancy sidebar. Unfortunately, a custom drawer also means that the contextualActions won't be displayed at all on mobile.
This isn't a problem for NeoChat, but I tried to add a sidebar with the variable in Kalgebra mobile and while this makes the interface much more powerful on the desktop it also breaks the mobile usecase.
Probably it would be a good idea to only move the actions to the context Drawer if it is a Kirigami.ContextDrawer and otherwise move the context actions to the top like on the desktop.
