When you are new with WinSCP you will be a little confused about too much icons with round arrows. I created this one for "Synchronize Browsing": <invalid hyperlink removed by admin>.
What do you think?
(If you are glad for more ideas: For "Compare" you could use a big ? over the Folders instead of the arrows, for "Keep remote up to date" a =
So the round arrows are clear for synchronizing.)
