Visual during switch
- A kwin effect
- Full screen busy -> to black -> to back in

Triggering
- kded module that keeps track of form factor
  - right now is an envvar .. meh
  - runtime platform string(s): [device], [form], [input]
- DBus signal on change
  - read from shell definition package
- keeps track of active shell definition package
  - default in the kded module's configuration
  - DBus API:
    - stringlist runtimePlatform
    - signal runtimePlatformChanged stringlist
    - string currentShellPackage
    - signal currentShellPackageChanged string
  - Auto-switch on hardware events
    - sources: libsolid, kscreen
    - Docking events
      - Screen plugging
      - Keyboard/mouse
- KCM switcher between desktop and netbook ported to this

On-screen keyboard
- Don't show when hardware keyboard available

KCM
- Manual switch between shell types

-==definitions==
+* Visual during switch
-* ''shell'': the binary that loads full screen and displays desktop, panels, etc. currently those would be: plasma-desktop, plasma-netbook, plasma-device, etc.
+** A kwin effect
-* ''workspace'': a full arrangement of shell (+ default layout), window manager, GUI utilities (e.g. krunner) and infrastructure processes (kactivitymanagerd, e.g.)
+** Full screen busy -> to black -> to back in
-==Workspace definitions==
+* Triggering
-Workspaces should be defined by self-contained Plasma Packages, one per workspace setup, containing:
+** kded module that keeps track of form factor
-* processes other than the shell and window manager that are required (e.g. krunner, software keyboard)
+*** right now is an envvar .. meh
-* QML layout to use (perhaps also included in package?)
+*** runtime platform string(s): [device], [form], [input]
-* kwin configuration
+** DBus signal on change
-* other application configuration (krunner, e.g.?)
+*** read from shell definition package
+** keeps track of active shell definition package
+*** default in the kded module's configuration
+*** DBus API:
+**** stringlist runtimePlatform
+**** signal runtimePlatformChanged stringlist
+**** string currentShellPackage
+**** signal currentShellPackageChanged string
+*** Auto-switch on hardware events
+**** sources: libsolid, kscreen
+**** Docking events
+***** Screen plugging
+***** Keyboard/mouse
+** KCM switcher between desktop and netbook ported to this
-==Track workspace setting in a kded module==
+* On-screen keyboard
-What is the current workspace will be tracked by a kded module. Features:
+** Don't show when hardware keyboard available
-* auto-switching based on triggers.
-** screen change
-** docking
-** custom user signal?
-* manual switching via dbus (perhaps tied to window manager; see secdtion on kwin)
-* dbus signal emitted when workspace changes
-** shell may load a different QML layout
-** kwin may change settings
-* start/stop processes according to workspace definition.
-** e.g. "desktop" will want to start krunner; switching to "netbook" which does not include krunner in its definition would result in krunner being stopped
-** re-use session management for this? some custom configuration system? modified startactive? systemd? or ...?
-==plasma-device becomes the only shell==
+* KCM
-All the shells will be replaced by an upgraded plasma-device.
+** Manual switch between shell types
-* control UI (add widgets, e.g.) will move into the shell QML, just as it is with plasma-device now in Plasma Active.
-* will listen to the workspace change signal from the kded module and possibly load a different workspace QML structure
-* the following features from plasma-desktop must be ported:
-* multiple panels
-* multi-screen awareness
-==kwin==
-* kwin will need to be able to source different sets of configuration files and change it's configuration in response to the signal
-* an elegant desktop effect to make the workspace UI reshuffle smooth
-** a simple fade to black with a busy spinner , followed by a fade back in would be enough
-** requires that kwin is the first process that starts switching
-** requires that kwin controls when the change signal is emitted to other processes
-** requires that applications provide feedback as to when they are finished transforming to trigger the fade in
-** unload/load window decoration, currently either a decoration is required (desktop) or hard disabled in code (active)
-==application integration==
-would be fantastic if applications can also adjust; e.g. okular switch from desktop to touch UI on workspace change.
