Pinning is not the same thing as tagging. Tagging is great, but the ability to pin messages so they always sort to the top of the list is extremely important to me. Pinned messages serve as reminders or to-do's--important things I always see first--especially in the Inbox when I launch Thunderbird. Filtering by tags just doesn't get it as it takes extra time and clicks, and out-of-sight is out-of-mind. Pinning is a common thing and I'm sure the developers can do it. It greatly contributes to productivity and with ThunderMail coming I would think productivity would be an important issue. ''PALEEEEEEEZ'' add pinning to Thunderbird! Thank you!
