I have found a bad behaviour when there are new files with the same name as previously deleted files.
So the behaviour is currently as followed:
If I have file with some versions of it and then I delete it, it gets into the recycle bin. Then later I create a new file with the same name (in the same directory). Then the old file gets removed from the recycle bin and there is also at the new file (with the same name) no version history of the old file. So after a new file with the same name is created there is no way to restore the old file.
So to fix this either there should be the old file kept in the recycle bin or in the version history there should be also the history of the old file.
I hope this feature can soon be implemented.
