This task represents the work of implementing v0.1 of the Suggestion Mode toggle.
For more details about the broader arc and scope of this feature, please review T415589.
Story
As an experienced volunteer who has enabled the Suggestion Mode beta feature, is using desktop VE, and who most often arrives into editing with a clear change in mind, I'd value there being a way to turn suggestion mode OFF on a per session basis WITHOUT needing to go into Special:Preferences so that I can remain in flow and preserve the option of seeing suggestions in future edit sessions.
Requirements
Meta
- Platform(s): desktop
- Configuration
- By default, the Suggestion Mode toggle this ticket introduces will be in an ON state whenever people arrive into a VE edit session
User experience
- Introduce a button within the desktop VE toolbar that, when tapped, toggles Suggestion Mode, and the button, into an ON/OFF state
- See "Mockups" for details about how this button will look.
- When toggled ON, all Suggestions will appear
- When toggled OFF, the following will not be visible
- Suggestions
- The suggestion gutter/rail that is used to "house" suggestions
Instrumentation
- Log an event whenever someone engages with the toggle button this ticket introduces.
- Put another away: we want to be able to know: "What proportion of edit sessions involve people toggling Suggestion Mode OFF and ON?"
- Implemented as follows (more in T420245#11715957):
- Using the tool will log the normal tool-used action for feature:editCheckSuggestions
- Using the tool will also log feature:editCheckSuggestions, action:toggle-{on|off}
Mockups

| ToggleButton OFF | ToggleButton ON |
When suggestions are OFF, we will use the cdxIconLightbulb icon. When suggestions are ON, we will use the lightbulb icon with an active indicator, representing that suggestions are turned on. The active version keeps the same lightbulb shape and size but including small spark elements around the lightbulb that expand outward in a subtle animation to indicate it is turned on.
Acceptance criteria
- Requirements are implemented
