I started diving this year, and just purchased MacDive.
Although I don't have my own diving computer yet, I still enjoy a lot to be able to keep a log of my previous dives, and I love features such as photo import, statistics and graphs, GPS localisation of dive sites ... So thanks a lot for your work !
There are a few things that I'd love to see appear in future updates, so here are my 2 cents :
- Dive number column in the "All Dives" view (I read that you're going to implement dives number in the next update).
- Contextual menu with choice of country flag when creating a new site, just so that we don't modify the flag resource in the contents of the MacDive.app !
- Photo folder / iPhoto event or album importation that keeps photo order (currently it seems to import them randomly, and it's quite a long task to re-order hundreds of photos manually).
- Ability to import and play movies as well as photos (.mov, .avi, etc ...) !
- Coverflow style photos display in the profile data section of the "All Dives" view (maybe with a tab for choosing to display site main photo, dive photos, or notes). Because as I don't have any diving computer yet and hence no profile data, my photos don't appear there. And it's a bit annoying to go to the edit / info window to be able to watch them ...
There are a couple of strange behavior I also wanted to report :
When editing a dive's date and time while dives are sorted by descending order in the "All Dives" view, the dive doesn't seem to update to its new position by itself and stays at the top of the column. I have to click twice on "Date" to re-sort the list, and only then it updates its position. Not a big deal, but worth noticing ...
Also, when I try to import photos, with the "Store images instead of paths" option on, the database grows much bigger than the actual photo size, (as you mentioned somewhere else), but when deleting them from a dive, the database doesn't go back to its initial size. Not a big deal either, I now link them to my iPhoto library (again, link to iPhoto events or albums, and order of photos preserved would be top notch), since a 1.2 Gb database slows the app too much

I'm sorry if these bugs have already been reported, not my intention to make a redundant post ...
There, I leave it to you, but thanks in advance and keep up the good work !
