The version adapted to 2.1.2 firmware is almost ready and I will publish it next week. More options for managing was introduced so using some notes as templates can be emulate more easy.
I still not think about synchronizing. Regarding to dropbox, probably wget should be used in one direction. I found a script (
Dropbox Uploader), which is suitable for the uploading, but it requires
cURL app, which is missing on PB. I hope it is easy for porting because there is libcurl.so in PB libs, which probably contains the core cURL functionality. Just we should ask someone from this forum or russian one to port it.
