Examle: I have to search for an attachement from a special sender - in 3 seconds I have with the thunderbird e-mail-search a list with all e-mails from the special sender, but I can not see which e-mails contain attachements. If I could select the column "number of attachements" it would be so helpful: 0 = there is no attachement, it makes no sense to click and open it: 1.) I have to close this wrong-opend-window and 2.) I have to switch back to the search-results-window because now I am in the main-thunderbird-view. Some companies always send their logo as attachement = no problem: once I have opend one of the e-mail-search-results I can see: oh, they always send a logo, so I have to search for e-mails with 2 attachements and so on. (Please apologize the word "sick" in my question: I am not so good in english, the row was so short and I did not know that I can write details too.)
