Personally, I consider a log book to be a personal thing. It's for no one but yourself except in the (in my experience) exceedingly rare instance that someone will demand you to present it. As such, IMO it shouldn't limit what kind of info you put in. A rigid structure may do just that.
Couple of questions:
Is having a graphic and some set fields for Bottom Time, Depth and Stop going to limit your ability to log dives other than those of simple square single-stop variety?
Do you ever breathe anything other than air? If so, where do you put it? Would you rather call your consumption fields "Gas In" and "Gas Out" so that it doesn't say Air when you are on EANx?
While the little column at the left is cool (checkboxes for conditions), are the particularly useful? Personally, if something is worth remembering, I'm going to write it down. Simply looking at a page and seeing "this was a dive with waves" wouldn't tell me anything.
What is the purpose of the "verification signature" field?
I used to maintain a logbook, but I found that as I learned more about diving I kept changing it around because each rigid structure limited me in one way or another. Now I just fill out a line-item type of log, and only for dives where I think there is something worth recording.
My main columns are:
Date (yy-mm-dd)
Site
Max Depth (ft)
Run Time (min)
Average Depth (FSW)
Prior SIT (min)
Deco Level (FSW) <-- Average depth that goes into decompression computations
Bottom Time (min) <-- Time that does into decompression computations
Bottom Mix
Decompression Profile (Gas: Time/Depth) <-- eg: 21/35: 1/110 1/100 1/90 1/80 EAN50: 4/70 4/60 2/50 2/40 3/30 10/20 5/10
Notes and Comments
The Deco info and the Notes and Comments are the big ones.
