There are situations in which the "Scan" button is disabled (grey).

Like when the "Clusters" ''folder'' is selected or when nothing is selected.

It would be nice that

• when '''nothing is selected''', the "Scan" button would '''scan all files''' and that
• when the '''"Clusters" folder is selected''', it would '''scan all clustered files'''.

It would save some clicks and some time, wouldn't it?

It seems to work on clusters now, but the scan button is disabled when nothing is selected.
