Problem:
When you open Thunderbird for Android with multiple accounts set up, it always defaults to the Unified Inbox. Users who primarily work in one account must manually switch every time, adding unnecessary taps and risking replies from the wrong address
Why It Matters:
Primary‑account focus: Most people have one “main” mailbox but still need others for reference or backup.
Efficiency: Opening the same inbox each time removes friction and speeds up daily workflows.
Accuracy: Guarantees replies and compositions use the correct identity, avoiding embarrassing mix‑ups.
Proposed Solution
Add a new setting under Preferences → General (or similar) for “Default Start Folder,” with options such as:
1. Inbox of Account X (selectable per configured account)
2. Last‑Viewed Folder
Benefits
One‑tap startup in your preferred mailbox
Reduced UI noise by bypassing the Unified Inbox when it isn’t needed
Fewer mistakes when sending mail from secondary accounts
