Add additional categories within overview
There are a few additions I think might help within the overview section
Within Dive Type I think a Wall option would be relevant - It kind of falls outside of drift as you can drift a reef or in the blue and I would suspect a lot of dives would sit nicely within this category
Also within the water type would adding a pool section to cover training dives and chlorinated water be worthwhile? It would allow for a clearer classification of Sea, Lake/river & Training in the pool.
