chamamento is a fansite type of theme by codematurgy, meant for those like me who aren’t actually that good at making sites pretty by offering alternatives to crafting headers and thumbnails:
add a header(synchronizes with default header or you can add a custom one)
make header full-width always, only when it reaches a certain screen size, or never at all
choose to align header text on top or at the bottom when using a header image; includes options that besides aligning will also center or hide it on mobile
choose to repeat header image horizontally or not
choose to add a dark screen over the header image(for contrast) or not
limited color choice(for those who don’t want to spend that much time picking colors!) linked to your Tumblr’s default colors, though allow custom values anyway
sidebar sections including updates, showcase, links(two of these!), social media, members and site information
add a custom font for headers and the likes
pick between four font sizes(13 to 16 pixels)
5 post size options(500, 540, 600, 640, or 700 pixels wide)

while NPF posts aren’t completely supported, i wouldn’t recommend creating text posts with titles through the app or you won’t get the title in place of the post date at the top of the post.
this theme does not include the options to hide captions, tags or the searchbar since it seems to defeat the purpose of this blog type.
you can see a preview of the theme here, while you can grab the code on Pastebin. the complete guide to customizing can be found here, as a page on the preview blog.
