Feature: Reset Individual Settings

[rhyslutsky]

Is your feature request related to a problem? Please describe.
Currently users can "reset app settings," which reverts all settings back to their default values including any user-defined phrases. Users should be able to reset individual settings to default values and keep other settings as-is. Kylie’s concern was preserving content while resetting settings (or vice versa); profiles would address this

Kylie out until Tuesday 11th August; final call deferred to her

Describe the solution you'd like
1.DECIDE: which of the below will need "reset" buttons and dialogs: Figma of Sketch of Designs
Option 1- Simple
- Two reset buckets proposed:
- Categories and phrases (preset + user-added content)
- App settings (toggles, timing, voice selection, selection mode, etc.)
- Descriptive footer text under each option to clarify what will be reset
- Reset ALL App Settings in separate area under these buttons in alert type color

   **Option 2 - More Granular**
      -  Preset Categories and Phrases 
             - reset order of categories
             - reset hide/show of categories - 
      - User-Added Categories and Phrases 
           - remove added categories - NOTE: will delete their phrases
           - Within each category, reset / delete ALL added phrases
           - Category = "Recents", reset removes all.
      - Timing and Sensitivity 
              - [Hover time will reset to 1 second ('Dwell Time' is reset to default =1000L) AND Cursor Sensitivity will reset to Medium (default =medium (0.1F)]
      - Selection Mode (will toggle Head Tracking to on | default =boolean = true )
       - Voice (default = device voice selection)
       - Descriptive footer text under each option to clarify what will be reset 
        - Reset ALL App Settings in separate area under these buttons in alert type color   

2. Design the domain-level reset buttons on the screens based on the decision made above . Must get design sign-off. Must match accessibility design as rest of app.
3. On selection of "reset" a confirmation dialog is presented with cancel/confirm actions, stating that this is permanent.
4. On selection of "confirm/reset," the reset logic is triggered. On selection of "cancel," no changes occur
5. All selection are operable via head tracking or gaze selection and switch input in addition to touch.

Describe alternatives you've considered

1. Profiles and import/export raised but flagged as high-risk due to PII and privacy constraints
2. MDM-based configuration noted as a possible future path for clinic/hospital deployments

Here are some ideas for keeping settings without going Profiles route:

Addressing PII Concerns with Import/Export

1. App-Level Encryption/Decryption
   Import: User selects encrypted settings file → app decrypts locally → applies settings
   Export: App encrypts settings locally → user downloads encrypted file
   PII Mitigation: Data never transmitted unencrypted; encryption/decryption happens entirely on-device
   User Benefit: Settings are portable without exposing personal data
2. Selective/Sanitized Export
   Option A: Export only "safe" settings (app preferences, timing, voice selection) and exclude user-defined phrases
   Option B: User manually selects which categories/phrases to include before export
   PII Mitigation: User controls what leaves the device; sensitive content stays local
3. Local-Only Storage
   Export files stored only on device or user's personal cloud (Google Drive, OneDrive)
   No cloud intermediary managed by the app
   PII Mitigation: Your app never touches the exported data after export

MDM-Based Configuration (Future Path)
For Clinic/Hospital Deployments:

• IT Admin Control: Administrators push settings via MDM (Intune, Google Workspace, etc.)
• No User Export/Import Needed: Settings silently apply to devices
• Compliance-Ready: Full audit trails, centralized policy enforcement
• PII Safe: No user-level file sharing; IT manages distribution through secure channels
  Implementation Path:

1. App accepts configuration from MDM provider
2. Validates and applies settings on app launch
3. Prevents user reset of certain MDM-enforced settings (optional lock-down)
