I've got two new requests (to add to the others I asked for before

- Dive Finish Time:
This is maybe a bit of a lazy thing to ask, but I still keep a paper logbook, and used MacDive's data to fill the times, temperatures, etc. Right now I have to calculate the dive's finish time (adding the original time + dive time). Could this be a new column with basically a sum of the two items mentioned before.
- New Category under Libray called Dive Operators:
This one it's a bit trickier. Every year I do one BIG dive trip (usually abroad from Spain and to a place I've never been before) and then, a couple of other smaller trips to places I've been before, so I'm a repeating customer.
I usually use the Dive Operator area of the dive card to write the Dive Shop/Center I've been diving with during X amount of dives.
Example: The way I'm doing it it's manually selecting all dives and writing down the name of the shop in the Dive Operator field (again, I dunno if it's the correct area but haven't found anywhere else to put it). I though that having a new Library called Dive Operators/Dive Centers could keep it all a bit tidier (and normalized) so that anytime I go back to those places I only have to select them from a drop-down list.
Also it'll be good as this way in their info card I could all of their information (website, telephone, email, owner, ...) just in case I need it.
Kind regards.
