The new version of bubbles comes with NO native slimtimer support.
Slimtimer is not on the list of extensions. It is very easy to add
slimtimer to the My Bubbles window. Just paste
http://www.slimtimer.com/client/
in the URL: text field and click "create". It looks and feels the same
as the old version but it took me 20 minutes to figure that out. I
think it deserves a mention on the website, since the "Bubbles:
SLIMTIMER on the Desktop" instruction set is no longer correct.
