Please enter e.g. 

24°48'E 45°8'N

into the Search line and press enter ;-)
If you play around with other coordinate string formats you might 
realize that the algorithm used still doesn't recognize all kinds of inputs (and has other issues).

So one possible junior job might be to fix the functionality behind.

Andrew Manson has been working on the "editing" topic during the Google Summer of Code 2009.

He did a huge amount of work but it's not fully ready for production yet.

See:

While his original topic was "Annotations for OSM" the whole technical approach should allow generic 
editing in the end (like GPS editing, OSM editing, route editing, etc.).
The whole backend is based on what we call the "Marble GraphicsView".

This topic is definitely more complex than the coordinate topic.

We'd like to have those and there has been some work on these issues already. But we still need to 
put some work into it to get the Marble rolling ;-)
