Currently, if I have a group open and new headers are downloaded, they appear at the bottom of the window. If I had the list sorted by subject and click the subject header to resort, the list gets sorted in reverse direction because the previous sort was in forward direction. However, I'm not trying to reverse the sort. I just want to get the new headers into proper sort order. I would love to see some enhancements for this situation.
1. If headers had been added to the bottom of the list, then clicking the column header should be treated as if the list was unsorted (e.g. sort forward instead of reverse).
2. I'd love for groups that are open, but are not the active tab, to auto-sort when new headers are added. Then they would be ready to go without the need to click anything. I understand that it could be disruptive to do this if the user were working in a group. So, adding to the bottom is a good approach when the tab is active.
