Can I get some general hints on how to extend and modify the Blank theme for Magento2? I have created a theme module, I have added web/css/source/_theme.less and _extend.less, and I understand how to use . Past that, changing this theme seems completely unworkable!

For example, if I move the currency selector, it is no longer a dropdown selector but transforms into a huge list of currencies.

If I try to change the navbar color, no matter how many color variables I override, none of the submenu colors actually change.

I have no clue how to change the catalog Add to Cart button action to "customize" instead of "addtToCart". If I just insert the Customize button block into an extending layout xml, nothing appears.
