It should not poll for a connection many times, I have to check that. I could somehow figure from dbus when device is put to sleep and do nothing, but most might want it to continue sync when screen saver hits in and sceen goes blank. So how should I predict when you want and don't want it to do stuff when you but the screen blank? Or was this just the issue what is should do nothing when wlan is lost?

Also it should not fetch metadata for the main view every time a sync file is completed, I should have different code paths for normal and synced transfers. DL does not fetch metadata even if you instantiate it from the main ui, UL will alter the folders content and then it will fetch. It should not however do it if the UL is done via sync. But I will have to check for that too then.

Thanks for the report, these things are especially important to tell me. As I don't use my own app for nearly anything, it's all for you
