Gas Cubby v2.7 UI issues

[MyFocusST]

I used v2.6 once - the version where you could not see the date spinners at all. I checked and saw v2.7 is available, so I upgraded, and can now see the date spinners when entering the date for a fill up.
The following comments are for v2.7 running on an iPhone 5 on iOS 7

Why even have date spinners? Could we not just have a calendar selector?
-- but this is probably the lowest priority of the issues
1) when entering cost and gallons, the entry row switches to white text on a grey background. It is hard to see what you are entering. The rows you are NOT ENTERING are easy to see -- Black text on a white background.
2) on the "notes" screen, there is no insert cursor visible -- either when typing or when trying to move the insert location with the magnifier. I am guessing where I will be typing.
3) and while discussing the notes page -- why is the text entry area smaller than the space available above the onscreen keyboard? There are big grey areas above and below the text entry area, so I am scrolling all the time. Let me use all the screen area!
4) and if I do have a lot of text, where are the scroll bars for the notes area?
5) why not give the option to hide the keyboard and see the whole notes (yes, this is not a bug, it is a feature request)
6) finally, why are the little check marks that indicate a row is selected (like in Tags) now green? They are harder to see. Just make them black again, so I can easily see them.

I like Gas Cubby and have been using it for years now. I want to keep liking it (or I would not take the time to write this). I put up with problems 3&4 in the old versions. To get a new version that still has these issues, and a bunch more when simply entering my first fill up after the v2.7 upgrade, is disappointing.

Can these things be fixed?
