The fact that the globe is collapsed now shows that there’s a bug somewhere, though.
I had the same problem.

I really like the way Adobe does that - and I’ve seen many other programs
do it the same way. Having no tags selected could be a way to see all
your dives that have no tags. But in reality it’s much easier to see this
as a filter. No filter selected means you see all dives. Then you select a
filter and you see the dives that have that tag.
Now the question becomes “is this an additive or a subtractive filter?”
I.e. is it an AND or an OR of tags that you select?
If I select “boat” and “photo” do I get the dives that have either of them
or the dives that have both of those tags?

Don’t. It usually means that there is some issue with the implementation
and you just haven’t managed to trigger this again. I haven’t had the
time to play with this enough - I’m spending way too much time on the
infrastructure right now and will do so again today - in hopes that after
this investment things will be much easier.
Famous last words.

See above. I’m not sure, either. When you start from all tags on then
you kind of have to do OR. When you start from all tags off you can
do either. I can see a user wanting both behaviors.

We definitely need a different UI. Thomas knows that :-)

I use lightroom a lot. I liked the tile layout but Thomas convinced me that
that wasn’t a good way to do things here. Basically when you look at 
photos then a thumbnail gives you 90% of the information about what you
are looking at. For dives that is not at all the case. Most dives have rather
predictable profiles. You want the date, the location, etc. So I was initially
excited by your idea, but I’m not sure anymore

Having said that, the checkboxes are ugly. And the “all of them are on”
implementation is just backwards. Trivial to fix, though.

I don’t have the time for a beautiful mockup…

Imagine having all the tags, alphabetically ordered, each with a gray
bubble around it. You click on one, the bubble turns blue and that tag
is selected as filter.

The bubbles look just like the ones we are using for tags and the likes
on the Notes panel.

Makes sense?
