Excellent! :-)

A couple of notes:

* The note is prefixed by a colon (actually ': '
* The sorting of columns seems to be alphabetic, so when you sort by temp,
you get 1°C, 13°C, 15°C, 2°C...
* If no divemaster or buddy is not set, then it shows (null), perhaps --
(as in the temp)?

Suggestions:
* How about adding another column with the location
* In detail view, make location as well as each tag a link as search?
