The tooltip option can easily be migrated to the notebook level, where it'll
affect everything in the notebook:
CreatePalette[
Tooltip[Button["Button", Appearance -> "Palette"], "Tooltip"],
TooltipBoxOptions -> {TooltipDelay -> Automatic}]
Unfortunately, Button's Appearance option cannot benefit from a similar
treatment because Button[], by default, hardcodes the value of
ButtonBoxOptions->{Appearance->Automatic} at the ButtonBox level, which
overrides anything specified at the notebook level (there has been discussion
about changing this in future versions).
I would suggest just making a function called PaletteButton which creates a
Button with the right options.
