I started with an almost completely empty theme and have been building up the templates and template parts in the Site Editor.
Now I need to be able to save the intermediary stages of the theme development.
I don't want to save the files as template and template part .html files since these would be automatically loaded as part of the theme. Is this a silly idea?

Alternatives:

1. Deliver the minimal part of thisis as a new theme called minimal. Similar to emptytheme but even less.
2. Store the exported templates and template parts as .htm files
3. As 2. but provide a mechanism to load them as patterns.
4. Store the exported templates and template parts as .html files anyway

Consideration

• I'm already storing screenshots which make the theme rather large
