Thanks! I have managed to reproduce this, should be an easy fix.
BTW, there actually should be no toolbox icon in the per mode state list just for this reason.

Now for the older questions:
As a public transit API from Google seems to be nowhere in sight, raw GTFS support might indeed be the only way of supporting public transit search/routing. Or maybe is there someone other than Google providing search over the publicly available GTFS schedules already ?

Batch download uses persistent connection to limit the (otherwise astronomically high) amount of open connections due to the huge number of tiles and their small size.

I might also enable this for automatic tile download, provided it brings some improvements, like faster tile loading.

As for some tileservers not supporting this - should be easy to solve by adding a few variables that enable/disable persistent automatic/batch download for a given layer to the map layer configuration file.

This is planned together with importing POI's from GPX files - for example, Cloudmade has huge POI database extracted from OpenStreetMap in in the GPX format.

The current module used by modRana for loding GPX seems to also support KML.

The API modRana currently uses supports this, but there is just no GUI for it yet.

Try to reinstall modRana ?

I have used Clutter for the currently released version of Mieru for Fremantle - while it is certainly usable it, Clutters performance is still not exactly stellar. Only version 1.0 is currently usable on Fremantle, while upstream is already somewhere around 1.7+. The newer versions require newer version of glib than what is currently available and need Gobject introspection for Python bindings, adding another heap of dependencies.

Thus to current plan is to use Qt with QML due to better availability on Fremantle, Harmattan and elsewhere.

Architecture

• QtGraphicsView for the main map widget
  This should bring better performance, enable things like fake a 3D, sprite markers, fluent rotation and zooming, etc.
• QML for the various menus
  What about finally having some kinetic scrolling, button feedback, etc. ?

As for the current GTK based UI, it should stay as an alternative for devices that don't have (recent) Qt libraries, like the Neo FreeRunner.

Implementation
The first thing to do is separate the GUI code from the modRana core (currently represented by the modrana.py file) and enable GUI switching and thus also serious alternative GUI development.

Anyway, might be quite a challenge but IMHO worth it due all the potential performance and usability gains.
