First of all, congrats on the release of EFB v2! It looks very nice and works great for me so far!
As a user of EFB v1, I have grown accustomed to its usage and the way it presents the information to me. Maybe it's just me being used to that version. I have a few ideas for improvements, if I may, that I think if they existed in v2 would make it a definite upgrade for me.
SID/STAR Overviews: I loved the feature where you could view all SIDs/STARs based on the direction of travel. This helped me tremendously to plan my departures and arrivals when appropriate, and gave me a good idea of which one to select or expect without having to view them one-by-one.
More prominent display of information: The way EFB v1 displayed chart information was very good. Things like frequencies, restrictions, courses, etc. were MUCH more prominently displayed, using bold font and larger text size. As it is now in v2, those same items are displayed in something like a 12pt, non-bolded style making it very difficult to find those items at a glance.
Different color between phases of flight: It would be great to have the SID/STAR portion of the route be highlighted in a different color than the approach phase, for example. As it stands, it's difficult, if not impossible, to determine where a STAR ends and the approach begins.
An option to disable collapse of non-selected procedures/runways: When I select a runway, SID, STAR, or approach, all other options are removed until I deselect the one currently being viewed. This may make it a bit cleaner, but for those like me who use the EFB to help plan a flight, it's a bit unfriendly to have to first deselect something to be able to select something else. I think an option to disable that behavior would be great.
Add OK/Close/Select buttons where appropriate: In various windows, there is no option to just close them without applying changes to your flight plan. I may want to view a procedure in full without extra windows open to make it easier to view. As it is, I have to keep the window open, or use the X in the top-right, which isn't very touch-screen friendly in my opinion.
The proposed cruise level should be appropriate for direction of flight: In EFB v1, it would give you a little reminder of whether to use even or odd flight levels. In v2, it doesn't do that at all. If it's going to propose a cruise level, I think it should also follow the general rules of direction of flight.
These are the ones I can think of right now. I'm currently using the demo of EFB v2 and will continue to use it until my trial is up. I would love to be able to upgrade as I genuinely appreciate this software, and LOVE the new features of the ground charts especially. But, right now, I'm not considering purchasing v2 until some of these things are addressed. I'm hoping this constructive criticism will only improve what is already a VERY nice piece of software!
