First check which tile storage method are you using in options->map->Tile storage. You want to use the "files" or else ("sqlite") modRana will looks only in its sqlite tile database and will ignore all tile files and folders.

Also try to check if the tile structure you get from is the same as the one used by modRana in the other folders.

There should be no problems with the lower zoomlevels (modRana actually currently has no lower limit on zoomlevel number ).

Also, to check if modRana is actually using your tiles, you can disable automatic map tiles download by setting network usage to "only for important data" in options->network->network usage. If new tiles show up after setting this, they are loaded from local storage.

ModRana currently simply logs to stdout, so you can just start it from xterm and look at the output it produces. The output can be also saved to a per-session log file.

I took a second look on the modRana code that stops redrawing when the window is minimized and/or the screen is blanked. Turned out I forgot stop the function for invalidating the window content - the redrawing was paused but the X-server was still getting damage events.

This should be now fixed in V0.23-1, also, as a result of this, the thumbnail in task switcher is no longer black - it just freezes on the last shown frame.

So there should now be no graphic related activity originating from modRana when the modRana window is not visible - so please let me know if you still get those freezes when modRana is minimized or the screen is blanked

You mean that during the turn by turn navigation, the voice says the "in 8 meters do something" but the actual distance is much longer ? How much longer ?

Yes, this would be possible to add - espeak provides multiple slightly different male and female voices. But I still think the default voice sounds the best

Yeah, the "modes" are pretty much work in progress. The basic idea is to have an optimal interface for each use case. This means mainly a configurable per-mode UI elements layout. You might want larger zoom buttons while driving the car but not the route elevation widget you use while mountain-biking, etc.

The modes are currently also used while looking up routes - note how you get different routes when you are in the walking vs car modes

So the first step is to make the interface interactively configurable & make the widgets usable again.

I was also thinking about per-mode specific settings, like: Scale the map to 4x original size, but in only in the car and bus modes, in bike mode only by 2X and use the default for all other modes.

Definitely planned (with a quite high priority too ) - modRana has all the needed data available through the Google geocoding service (note how there is an estimated start and destination address for P2P routesa lready), I just basically need to extend the UI to show it.
