PLEASE make saves votable from the site.

Surely you need to actually play with a save (i.e. open it in Powder Toy) before you can make a fair decision about whether it's worthy of a vote?

You can switch from sorting by votes to sorting by date by adding "sort:date" to your search query.

I'm not sure what the point of sorting by views would be, I don't think the view counts are particularly accurate anyway.

A website which lets you search in titles only or tags only (add "sort:votes" or "sort:date" to sort by those things; tags and votes might not be up to date):

Tags only: http://powdertoythings.co.uk/Powder/Saves/Search.html?Search_Query=search%3Atags+nuclear

Title only: http://powdertoythings.co.uk/Powder/Saves/Search.html?Search_Query=search%3Atitle+nuclear
