• Summarize discussion on Add 'Help' icon for sync conflict #17544 (comment)

[himanshjangra1]

1. Issue: Add a “Help” icon to the Sync Conflict dialog in AnkiDroid to make it easier for users to understand and resolve sync conflicts.
2. Goal: The icon should link to an explanation — ideally an AnkiDroid-specific help page instead of the generic Anki manual.
3. Discussion: Contributors debated between using an external link or an in-app dialog; in-app was preferred for better accessibility and user experience.
4. Progress: Several contributors showed interest, but work stalled; later, @sakesane proposed a simple design with a help icon and concise in-app explanation.
5. Current Status: Issue remains open and is blocked until the related documentation page (ankidroiddocs#166) is updated; final plan is to add the icon and link first, then refine dialog content in a separate issue.
