More Manifest Customisation Issues

Hello,

I’ve manages to customise a lot of the manifest theme from following various threads here in the forum. (thanks!) I just have a few things that I’m stuck on now.

Firstly I created a custom menu, and I’d like to be able to link both to pages within wordpress and external sites (i.e my main website). I’ve created the menu and listed all the things I’d want to appear as the ‘tabs’ on the navigation bar. But I can’t seem to overide the navigation that was already on manifest when I installed it before creating the custom menu (hope that makes sense?)

Secondly and I’m not sure if this is even possible, but I’d like to change the font of the post date how can I do that?

Lastly (I hope!) is it possible to move the search bar the the navigation? Perhaps for the search box to appear under the word ‘search’ whilst hovering over it, like a drop down menu?

Thanks in advance, sorry for the length of this!
