I use Evernote for making 'to Do' lists and quite often they can get quite big. Once I have completed a job on my 'to Do' list I usually leave it in the list because it takes longer to delete a completed job. After a while the list has lots of checked check boxes scattered around the non-checked check boxes and the list hasn't become any shorter.
What would be nice is if there was a menu we could go to and purge/clear all checked check boxes within a note so that it can be tidied up.
