The new message list/message table is able to accommodate only about half of the previos amount of messages in the example <https://translatewiki.net/wiki/File:New_interface_bugs,_German,_7.png> Of course the comparison is not entirely fair because on old interface to see English source you had to double vertical space consumption, on the other hand the new interface truncates text.
The current whitespace is part of the design.
