I added a few lines of code to maemo-mapper v0.2.1 to make 'Download Maps by Area' easy to use:

The coordinates of the current and previous View Center are automatically filled into the fields for Top-Left and Bottom-Right Latitude and Longitude in the 'Download Maps by Area' window.

Thus, to download an area, just tap two opposite corners of an imaginary rectangle on the current map, and then go to the menu 'Maps' -> 'Download Area...'. The corresponding values will have been filled in. Of cause you still can edit them. Now the only thing that remains to be done manually by you is to select the Zoom levels on the second tab of the window. (Being at it, I also fixed a bug in the new download confirmation dialog.)

Please consider my tiny change as a proposal to implement item 12 on Guite's TODO list for future versions of Maemo Mapper: My change is only 26 lines of Gnuite's v0.2.1 source. A source code patch can be found here: http://armin-warda.de/maemo-mapper-0.2.1-aw-0.1.patch For testing, a package with this patch applied can be downloaded here: http://armin-warda.de/maemo-mapper_0.2.1-aw-0.1_arm.deb.
