Each of the smaller frames (e.g.Local Filesystem) has
help text when you place your mouse over the tool icons
e.g. 'Change Directory'.
The main toolbar does not have this feature - although I
did notice after a while that help does appear along the
bottom taskbar - but that isnt consistant with how the
rest of the app works.
It would be nice if this feature was added, as the icons
feel a bit misleading.
