User defined tags are a great way to enter custom information without 
needing explicit support and/or a custom user interface for each type of 
information. Do you want to mark dives as a night dive? Just create a 
nightdive tag. People who don't care about nightdives are not annoyed by 
a useless (from their point of view) nightdive checkbox. Of course this 
is not limited to night dives :-)

I would even vote for supporting a hierarchical tag system, so you 
easily categorize your tags. For example separate group for marine life 
sightings (with subgroups for species as you wish), another group for 
dive type/purpose (wreck, training, deep, photo, etc), and so on.

Long time ago I made a prototype UI for this. The screenshot should be 
self explanatory:

Might be useful to compare the same algorithm, but with different 
parameters. For example comparing the effects of using different GF 
factors, using another gas mix, etc.
