Good morning / afternoon / evening to everyone.

I'm currently working on a eCommerce shop that will have full width banners displayed on homepage. I managed to make a working (and looking close to what designer wanted) snippet of it using modified Bootstrap carousel.

Now, my problem is that in order to add a new banner image and navigation dot I need to go to snippet code in module files and add it there manually then delete and add snippet again using Website Builder, but I would like to make it so that I can access some kind of page in Odoo backend (using <menuitem> in Python code?) with a list of banners displayed so that I can delete and add new banners (upload image, add title, add alt tag, add optional link to another page etc.), maybe re-arrange them if needed.

Basically I need to make something like Master Slider (http://www.masterslider.com/) in Wordpress where I can easily manage them.

How would I even start making something like that? It doesn't need to be a snippet in my existing theme. I can make a new module if needed (it might even be more future proof, because I will be able to easily re-use it on another website later), but I have no idea what I should start creating (models, controllers, actions?).
