suing no no
on n900 it gets slow ofen mainly when left in background
one improvment i have found is no tile download failures as of late .
navigating menus is cubersome with up down arrows making them scrollable would be useful
slider or double tap for fast zooming in out
there should be a tile for map switching as its cubersome diving deep in the menu for it
clicking on maps is not possible so most info from osm is not usable as in marble i can click anywhere and select adreess info same for google maps i.e bus stops and such names are not shown only icon
ui style is nice but looks awful not complaining :d i am making a few icons in png if that helps
anyway i think as mapink is progressing these issues can be dealt later on
