- and I have many other virtual search folders, that have lost their function!!, I have to set again the folders in which mails should be searched for - it will take hours to make all folders working again

Hi There! just updated to a new thunderbird version (102) - and my workflow got totally messed up! Usability is a catastrophe -> Mails are Threaded - I DONT WANT THAT -> Virtual Search Folders lost their functionality -> Mails sent as an answer from a virtual folder, donT get into the right sent folder I have a virtual search folder (placed under Locale) called "current mails" where I see every mail from different mailboxes thats either 14 days old max , unread or marked important (with a star) ... had to recreate this folder after the update, because it was gone - and I have many other virtual search folders, that have lost their function!!, I have to set again the folders in which mails should be searched for - it will take hours to make all folders working again really the worst: When I send an answer to a Mail from that folder (the mail still is inside the correct inbox) , my answer mail doesnt get stored into the "sent" folder of the mail account - but into a "sent" folder of Locale!! WHY !!! Please help me there I am so heavily frustrated !!!! I am crying out loud "Total desaster - absolutely Unusable!" Really - I will change my Mail client within the next hours - I am Thunderbird/Firefox(Firebird) User from the first day! if that means something... Thanks! Hendrik
