Richard, thanks a lot for all your reports/suggestions. I believe I cannot help for many of these but here are some comments:

Let me quote from our source code: /* Most common AL cylinders */ { "AL40", .cuft = 40, .psi = 3000 }, { "AL50", .cuft = 50, .psi = 3000 }, { "AL63", .cuft = 63, .psi = 3000 }, { "AL72", .cuft = 72, .psi = 3000 }, { "AL80", .cuft = 80, .psi = 3000 }, { "AL100", .cuft = 100, .psi = 3300 }, /* Metric AL cylinders */ { "ALU7", .ml = 7000, .bar = 200 }, /* Somewhat common LP steel cylinders */ { "LP85", .cuft = 85, .psi = 2640 }, { "LP95", .cuft = 95, .psi = 2640 }, { "LP108", .cuft = 108, .psi = 2640 }, { "LP121", .cuft = 121, .psi = 2640 }, /* Somewhat common HP steel cylinders */ { "HP65", .cuft = 65, .psi = 3442 }, { "HP80", .cuft = 80, .psi = 3442 }, { "HP100", .cuft = 100, .psi = 3442 }, { "HP119", .cuft = 119, .psi = 3442 }, { "HP130", .cuft = 130, .psi = 3442 }, As you see, we indeed use the nominal sizes even though they are not exact. We had a discussion in the past (but I am not able to find it either in the mailing list archives or trac) if we should use the „real“ values as shown on that web page but ended up the conclusion that that would actually be even more confusing. > Adding full/empty buoyancy stats to the cylinder page would be really useful, > IMO, as we can't always control what we get with rental tanks. I was on > HP100s one day, AL80s the next, etc. The weight of the metal changes at least for different manufacturers so unless you weight your cylinder, which value are you going to use? The weight of the gas is of course always the same. > #3 When I'm editing the cylinder sizes (and I assume all over the place > elsewhere), I have to enter the tank type, then select the volume, then make > the change, then click off somewhere else unrelated, then save.

A field is only changed when the keyboard focus leaves it (changing it with every keystroke would have strange side effects as you would end up with strange values in the middle of typing a number). But you can for example use the TAB key if you don’t want to change to the mouse. > #4 Dives exported from subsurface to divelogs.de <http://divelogs.de/> are > now showing an additional 0.1lb more than what they show in subsurface.

Alternatively use one of the existing fields for this (I for example never use the dive master field so I could use that for boat information if I wanted). The UI is already quite crowded so I think it is unlikely that we will add further fields lightly. > #6 Feature Request: Any chance of getting a SAC graph option? > > I think it would be useful to see where breathing went up, in particular > paired with other events there, like timestamped photos and other trackable > events.

Do you realize that the color of the depth graph is already a representation of the momentary SAC? Given the resolution of the pressure sensor I guess it would make little sense to present finer granularity than a color coding (there is only very limited numerical precision). Best Robert
