Include and exclude in metadata search

[joejoejoe3652]

Hi Pewpews, love the work you are doing!

It would be great if in future iterations, you can include or exclude keywords while automatically searching for tags. For example, currently for automatic metadata tagging, it would chose the first source, but that is usually the Japanese original one while the English title would be further up on the list. Instead of choosing the first source, could you implement a feature where it selects the source with the keyword "english" instead and if there is no english source, then tag using the first source it finds. This would make auto tagging a lot more accurate.

I love what you are doing and thanks for making this program!

I've been thinking about adding this since a long time ago.
