to move them in order to see what you miss, just press "alt" while moving the mousedev or ts.
in order to resize them.... i wish i know... i love gpsdrive in the desktop mode, but even with :
gpsdrive -s 480 -r 640 ... it doesn't become little enought. so launch it in pda mode ( gpsdrove -M pda) .... here it fit, but i dislike this mode
maybe the only way to resize them is to rtfs, and shape it ?
