With Thunderbird for Windows, my system shows total emails unread. In Thunderbird for Android, it shows 99+. Can this be changed to show total? I have emails I don't need to read, but need to keep them for records. ALSO Windows shows the total emails in a different color when there are new emails. This doesn't happen with Android version, or am I missing something? Can other colors be used besides light and dark theme? Selecting multiple emails to delete and the color change is very slight.
