Google is making priority markers default in Gmail.

MOUNTAIN VIEW, Calif.--Google is giving its Priority Inbox feature more priority.

Speaking here at the Inbox Love event, Gmail product lead Paul McDonald said the service's priority indicators would soon start showing up even in in-boxes of users who have not turned on the Priority Inbox feature.

Gmail users won't be forced into viewing their in-boxes in the segregated Priority view, but McDonald showed how the little yellow flags that indicate a high-priority message will soon be displayed by default in the standard, unprioritized view. Users will be able to train the feature by turning the indicators on individual messages on and off.

A new pop-up message will alert users on log-in to several different "in-box types" that users can select from. In addition to "Classic," users will be able to choose Unread first, Starred first, Important first, and Priority Inbox. The selection will be reversible at any time. McDonald did not say when the changes would be launched.
