There are good enhancements in this version, but the lack of
separator line beetween the buttons in the toolbars is
slightly surprising!
Not so!
From the main menu go to <View - Toolbars - Customise>
and add as many separators as you wish.
Addendum to the above - I personally think the new button style where they pop out when
covered by the cursor is excellent - it makes for more accurate navigation.
