I'm currently thinking about moving the search lineedit into an own toolbar 
(like a browser's search Url line). The listview would then likely become the 
"completion" drop-down list. 
I think that the autocentre should then be disabled.

Well I don't know about the interna of the OSM namefinder. Maybe Jens-Michael 
can answer this?

Well we shouldn't filter out results completely, but at least the sorting 
should be done based on where you look and based on the "result that will be 
most likely of interest to the user".

You mean that you can't find names in the data that has been downloaded? I 
guess that would have to wait until we have real vector support + routing cues 
in place ....
