Notes 8 Theme
If you like the old layout, go to File-
Preferences- Windows and Themes. You can switch to Notes 8 theme. After
restarting the client, the toolbars are consolidated and it's no longer
a separate bar.
Then, if that's not enough you can also
right-click near and deselect the search window. Then you can get rid of
the shortcuts one at a time by View-Show Shortcut Buttons and deselect
each one. At that point, you've basically got the complete Notes 8.5 look'n'feel.
