Version: (using KDE 4.1.0) Installed from: Ubuntu Packages Currently a double click does nothing in Marble. It should zoom in one level and center where the click was done.
Yes, this is on our TODO.
Created attachment 39705 [details] marble-doubleclick-zooms.diff Please test the attached patch. Besides zooming in at the mouse position on double clicks, it increases the timeout for the left mouse button popup a bit (from 250 to 400 ms) to give you a chance of double clicking without getting a menu in your way. The zoom value is 80, that should be equivalent to zooming in twice.
SVN commit 1080181 by nienhueser: Add support for changing the observer position via GeoDataLookAt objects (~ camera distance to some ground point). Generalize jump to target animations and use them for user interaction when enabled in settings. Implement double click to zoom in. Fix rubber band getting stuck when released over a float item.

Fixed in trunk, will be available with KDE SC 4.5. Too many changes for a backport to 4.4, I'm afraid.
