Suggestion: allow dedicated server directory (e.g. /clientsync) to be synchronised instead of root / only
The current version of the Android client can apparently "only" synchronise the whole root, everything below / from the server.
If you compare to the present Windows client 1.1.1,. this (by default, but can be changed) synchronises /clientsync subdirectory.
I suggest, that the Android client gets a new option parameter "synchronisation-directory" (default= "/clientsync"). On the device, the corresponding directory would then be /mnt/sdcard/owncloud/clientsync .
The main difference between desktop client and mobile client is that desktop client is downloading entire structure of directory with data. Mobile client is creating local index of remote files and downloads them when needed. However changing synchronization root feature is currently under consideration.
