Unchecking synchronized subfolder without local delete

[ts-mk]

Expected behaviour

If I select a folder ("A") to synchronize with server and later decide not to synchronize one of its subfolders ("A.B"), I might not want local files to be deleted. Just because I don't want something to be synchronized anymore doesn't necessarily mean I want it to be removed from my local machine.

Actual behaviour

Currently there seems to be no option to do that (apart from removing folder A completely and setting it up again while unselecting subfolder A.B) so it would be great if the user could somehow choose whether local files are to be deleted.

Steps to reproduce

1. Set up a folder to be synchronized with the server.
2. Later click on "Choose What to Sync" for that folder.
3. Uncheck subfolders that you don't want to synchronize anymore.
