I'm new to building apps for SharePoint in Office 365. I'm pretty new as a developer as well. I do know that Apps are now called Add-ins, but I'm using Visual Studio and the projects are still named with the old SharePoint Apps.
I'd like to create a SharePoint hosted app that gives me an interface to create a list (that I've defined) and choose which site collection / sub site to create it on. I don't want it on the app web.
I followed this tutorial and it kind of does what I'm looking for, but it creates the list on the app web.

I'd rather be able to create the list from the "Add an app" option under settings.
Currently, I can create a new SP app project. I see where I can create content types, columns, etc. However, I'm not sure where to go from there.
If this is possible for an SP hosted app, I'd prefer to use JavaScript, HTML, CSS.
Can somebody help guide me in the right direction?
