Some new bugs/misfeatures of new version

Hi,

Guys, thank you for you greate work.
Unfortunately, there are some new bugs and misfeatures.

I've already reported them to you and decided to post them here:

bug - as i reported, attachments with russian names are broken
misfeature - the "cross" button for deleting mail isn't available
misfeature - i can't sort mail by From address, the only columns i can are Date and Size
misfeature - in the previous version clicking on the Sender's name opened a new tab with all mail from that person, now it doesn't
misfeature - selection of the current message in the messages list is too faded, users can't see it and now they are looking for more darker theme in the settings

Please, fix ASAP, some of new misfeatures are very annoying :(

Thank you.

P.S. Guys, let's collect all bugs/misfeatures here.
