Hi
In general I agree with you, but for the specific purpose that i talk about (passing to Picasa just to upload) it wouldn't matter. Phoshare should do this just as a file operation, not synch. I mean, at the NEXT run if the option is off, additional folder are deleted and pics that were there are re-exported in the single dire (i tested this after splitting dirs manually), but i would mot care because i already did the upload.
In other words... i'm not asking synch... just post-synch file operation.
Anyway... your choice. Great app
Best regards
