OK, problems with folder solved (PDF, logbook), my mistake, but - maybe will be good make this setting little bit more user friendly ...

Somethign more - box with airfield info, probably, except increas info, can be good show there avaliable PDF's file and possibility to direct open ... ?
Manual - you describe there use of RMaps, but this sw not in Google play, maybe will be good put there link to google code, where is possible to find this ?
Something similar will be good about AIS, probably wiil be good link to seznam oEU AIS on eurocontrol + some other usefull pages, but it's only idea.
