Seconding the general "kinda like" ;-)
I also like that all the meta information pertaining to a thread (General Information, Environment Versions, Miscellaneos) is available - but the text area grows small when using laptop screen. A tabbed approach for the info currently all packed ito a single Tab/Page beneath the thread-tree would enhance "pure thread reading" reading a lot.
First tab ONLY for message lines plus a single concatenated line of From, To and Title
Second Tab/Page for the long version of From/To, with pictures if so set, Third Tab/Page for General Information, Environment Versions, Miscellaneos (fourth Tab/Page on replies for attached file info) would clean up the interface a lot while still giving near-instant info if needed or wished for.

Even better would be providing 3 "empty" Tabs/Pages and giving users the option to decide on where to display what info - some users might wish to keep current setup, others might want to leave out some info if using slow mobile connections. We are programmers here - almost as many opinions on best layout as people asked ;-))

//upd: clicking with "open in a new tab" gives a nice new relatively large browser tab with message. Perhaps - if giving users options on how to setup - for small mobile screens separating Thread tree from message might be even better - Tab1 Thread tree, Tab2 Message, Tab3 From/To, Tab4 Thread meta data, Tab 5 files on reply, Tab 6 left hand tools like search tools, Folders, replies would be set.

Of course device dependant: save DIFFERENT settings on smartphone, tablet, laptop, desktop ;-))) //end upd

I wasn't until I actually typed the www.LevelExtreme.com in the address bar that I realized the site had changed. Make the prior default page redirect to the new web address. Others may believe site is in trouble or is simply gone.
