Starting layouts and/or "cookiecutter" templates

[mgaitan]

While I understand the basics of CSS, it was never (and I fear never will be) my forte. In my first approach, as the "demo" app looked structurally quite similar to what I need, I reused its containers and css.

So, wouldn't it be nice to have a set of general layout templates to start? Or even better, a dynamically adapted copier or cookiecutter template that generates the boilerplate of containers and static widgets and their respective CSS to start a Textual application. For example:

Include header? yes
Include footer? yes
Include left sidebar? yes
Include welcome message ? no 
Include bottom panel ? yes

Do you think this is a good idea? Any generous volunteers?
