For those of us visiting from afar, would be great to have the option of setting a specific station as "Home." Could tap "Find closest station," then tap "Go Home" to avoid scrolling around infamiliar MRT map to figure out where our destination is.

(Thanks for the great app!)

If you are in wodoukou station, and are going toward xizhimen station, the major signs in the wodoukou station don't say to go to xizhimen. It would be nice to have the same directions that are easily available in the stations.

I would love to be able to add my own personalized notes for individual stations like the name of a company with whom I do business and the exit I should take.

I Would like them available only for me to see rather than "public"

It would be useful to be able to downvote tips that you know to be incorrect or outdated. Examples from the Beijing app include xizhimen - buying tickets to badaling info is incorrect; and dongsishitiao - distance to sanlitun is much greater than the tip says.

Update Seoul map.

The new Shanghai map has line 7 station as Middle Longhua Road, which is correct. The old version (which I prefer) has it still listed as Chuanchang Road, which it no longer is.

Create an app for Windows 8

I would like to be able to look at individual lines or select a small number of lines to view

From Hong Kong Central station to Lo Wu, your app suggests to change at Prince Edward which is not recommended. The correct station to change is Mongkok.

北京明天（2012年12月30號）新增4四條地鐵線，望儘快更新此App. 謝謝！

the position of line 9 and line 5 should be more close to the real position

Example: if I want to go to Ikea, what station do I get off?

Compass direction

Possible to have both SBS and SMRT buses integrated on its cost and time traveling from point A to B.

Android: It would be great to have only one of these programs on my device, but with multiple cities. Many people travel from Shanghai to Guangzhou to Hong Kong and would love to use your program for all these cities but don't want 3 separate filling their device.

Would be great to see the stops and lines on a street map to better understand where they go and know where to get on/off

Create a Map like the MTR map for the Hong Kong Ferries. This would be very useful to see where to catch ferries for which island and how long it would take and cost.
