I would like it to be possible to be selective about which screensavers gets to be in the random list. I have a few favourites but currently it is all or nothing.

A simplistic way to implement this would be to simply allow CTRL-selecting in the screensavers list, see attached screenshot for mock-up. It's not totally discoverable but OTOH it was the first thing I tried... and it could be mentioned in the help for those who look for it. Those who don't look for it will never notice.

A further step would be to have a separate GUI for this, but I'm note sure if it's needed. An even better way to do it would be to introduce checkboxes, that way individual screensavers could be previewed while retaining the list.

The preview screen turns to an informational banner, in case someone happens to do this by mistake. Could include some simple instructions too.
