[Enhancement] Add toggle for unmarked books

[Robin]

Would be nice if the marked menu offered a "toggle for umarked books" Right now have to select all then toggle for marked books which then unmarks the marked and marks the unmarked.

How does what you are asking for differ from the existing option "Mark all selected books" that was added in calibre version 7.8.0?

To invert a search. To find the items that DON'T turn up.

[Charles Haley (cbhaley)]

I don't understand. Invert what search? Do you want to do a search "marked:false" instead of a select all? It would be helpful if you provided a complete set of steps you use now to accomplish what you want.

I understand "toggle for unmarked books" to mean "set unmarked books to marked". Since setting an already marked book to marked does nothing, this is the same as choosing "mark selected books".

Note that you can invert a search of any complexity by putting the search expression in parentheses and typing "not" at the front, as in "not (marked:true)"
