We're going to have an 'include all' option for tags! :-)

I would also love to be able to filter down to more than one custom tag at once - I have one set of tags for genre, another for recommendation source, and a last set for method of reading (library, kindle, to buy, etc). It would be fantastic if I could filter, for example, my books down to g-mystery and s-library to see what I should pick up from the library!

I quite like the 'original publication year' - thanks!

There's a new range of sort options on the To-Read Pile, read books, owned books, tagged books, and the main filter. There's also a new 'original publication year' filter option. More detail in an upcoming Changelog post!
