Request:

In 'Mail' window, beside 'Select all' checkbox, have an 'unread only' checkbox.

Then one could could select all unread in one tick, then mark as read, delete, etc.

e.g. I often just delete the 'sent resources' messages, and mark all read the battle messages.

This gets painful when there are more than 20 of them. 'unread only' would help.

Thanks for listening.
