Hi, and thank you.
Just installed your app, it installs fine, and for me it's quite useful (actually first real life usage will be tomorrow )
If I may have a few suggestions re: user interface/layout:
1. Using a different theme (Marina) I get white lines and square corners around the two input boxes (the rounded corners are inside the square white corners). Basically it's like each input box sits inside a white rectangle 2px larger on both left and right, but same size vertically.
2. Regarding layout, in my opinion it would make better use of available space to have the input boxes, the search and today/tomorrow buttons on the left side, stacked on top of each other, with the large info area on the right. Input boxes should be smaller (3-4 chars at most for the airline code and 5-6 chars for the flight number). Labels would stay on a top horizontal line (Airline, Flight No and then Info - new label for the info text area).
3. Details should be a link, not a button. This is on the theory that pressing a button always keeps you inside the application, and people expect this. A link on the other hand signifies leaving the current place (the app). I'd also move it inside the text area, just above the 'Data courtesy of...' bit, and change it to 'More details...'
4. I wouldn't worry that dragging over the info text area selects the text, since it's useful to be able to copy/paste it in an email or a message.
5. This is just an idea, not sure if it's really useful, but.. Maybe the flight info can be parsed and displayed in a form/table instead of the info text area.
