ux: give focus to note field after tapping to add a note

Almost every time I make a tx, I add a note for my records. When you tap to add a note, you then also have to tap in the text field to give it focus before typing. It's just a small thing but after 100 times, it grates. It also happens to be slightly off my screen so I have to scroll up first.

Would be a nice ux improvement for those of us who need to document our tx.

Thanks for the feedback, we will look into a fix.
I can understand how the frustration can build up.
