Current stability of M8

[Andre Paradis]

Hi,

I'd like to know what is the level of stability of the 
current slide release (M8).

Also, when moving files between two collections, the files 
are logically moved from one collection to the other.  But 
physically on disk, the source file remains there.

So when one try to put the same file name in the source 
collection, we get an error because the file is present on disk.

Is this a correct behavior?  do we have to explicitly delete 
the file after a move command?

Thanks
