Bild provides 4 custom front pages for your future site. These are: gallery (as in this demo), galleries archive, project, portfolio archive. Here is how the Custom Front Page settings look in the Admin Panel:
You can create a dedicated gallery for the front page — and it will not be shown anywhere else on the site. That could be a brief showcase of your favorite works from different series.
If you choose to display a list of your galleries or projects on the front page, the categories menu can be hidden from it (and still be displayed on the Archive pages if you like).
There are more things you can customize in this theme — like colors and fonts.
