English feedback for the developper

I really appreciate your publishment of Japanese version of your lineup, but for now this is quite useless.
Here I list up some major defects I noticed.
1:Why arent the stations on the map screen clickable? It should link at least to the other features such as Google map and transfer route lookup. Link to stations internal map would be very useful.
2:The railway lines list is utterly useless. For what purpose is it implemented? It should be clickable to show the stations on the line. Nobody would use the search function on this small list.
3:The station list would be much more usable if it accept alphabet spelling and Hiragana spelling for search function.
