Please add "Mark Thread as Read" feature!

Hi Alex! When I try to use ^Unread^ filter, some threads still show up even if I mark the first message as read.

Will you please add the "Mark Thread as Read" feature along with a shortcut?

Thanks for updating this excellent software!

yes, maybe to put add more options for threads, internally there is a function already which does "thread" operations with only setting a flag, someone asked also for download thread option. the general idea was to minimize the number of menu options, since for many users the number appears to be excessive.
