except that if you delete files from that viewscheme you delete them for good, not just from the recently imported smartlist.
I don't think we're quite on the same page here. I'm thinking 'viewschemes', not 'playlists'.
If you select files in any viewscheme and press delete, you will get the 'delete' dialogue offering the three options:
remove from library
recycle bin
permanantly delete (remove from hard disc).
the default, MC maintained 'recently imported' is more a playlist than a smartlist. perhaps 'recently' imported was not quite the correct name for what I had in mind. 'date' imported would probably be more appropriate.
that example includes every file in the library. you could also make viewschemes filtered by media type, thus dispensing with the first pane, and choosing others more suited to the filtered media type. people/places/events for pictures, for example.
There's lots you could do to tweak this.
you could make an "imported in the past 7 days" viewscheme by adding [date imported]=<=7d to step 4
remove the year and month panes, replacing them with a day pane. if you use formatdate([date imported,0],dddd) for the day pane, you will get Monday, Tuesday, etc. rather 13, 14, etc.
Nice
