Generally-speaking, the conversations have always circled around features: There are those that believe every feature you could ever imagine should be included like text color, font selector, and more. On the flip-side, there are those that feel WordPress themes should be finite and extra features should only be added when it’s niche specific.
He says the the main problem is theme bloat, but I think it’s more about the lock-in effect some themes have on users. If they customize it or add content via functionality provided by the theme, then if they switch they no longer have access to it (although the content does persist in the database, there’s just no longer an interface to accessing it).
If users are stuck in your theme because it’s the only way they know how to show their content then it becomes problematic. I’m curious as to how often users are going around changing themes though. Are they changing themes for more/different functionality or for a new look? I find myself changing a theme every couple years or so to update the site, but that’s usually in a whole redesign phase and not just switching around for fun. Should theme switching be more frequent?
I also see it from the user perspective. They just want to purchase/install a theme and be running, they may not have the patience or expertise to 1) find the right plugin 2) install it and set it up, so they’d prefer it be in the theme as a package deal.
Partly, I don’t see it a problem including CPT info in a theme, because that’s where you have to style it anyways, right? Users want their post types, but they also want the templates and styles and functionality/integration with the site that go along with them, and I think a theme is the easiest place to keep all that for the developers as well as the users. Plugin shouldn’t have all the styles for the CPT content and can’t have the template files because then if they switch the theme the styles conflict with the new theme. They may end up having to learn CSS to switch the theme anyways. The users are going to want their data displayed properly as well as it be accessible on their site. So if a new theme would not properly display or integrate the CPT data, then why have it included at all.
Eric does offer some alternative solutions:
Offer a Support License purchase option that allows users to follow tutorials for their own customization.
Offer free downloadable plugins that work exclusively with your premium theme that adds easy functionality.
Offer tiered theme versions–beginner, advanced and developer.
I like the idea of including a plugin to add functionality, but I’d suggest that rather than making it exclusive, make it work with any theme, just make sure your theme supports it (along with other popular plugins).
There is talk about making extra theme functionality ‘opt-out’ for those experienced enough to do so. Set a variable in the functions.php file or even comment out a block of code to remove some customization options to it can be done via a plugin. This, although more work, seems like a good option. Providing the features by plugin makes sense, but asking beginner users to do that extra work seems like unnecessary friction.
Also, it’d be nice if WP had a built in UI for custom post types and custom taxonomies and even custom fields and meta boxes in core. Lay users could then easily create content types and manage data. WordPress would be a tool to create your own custom CMS. Theme developers could create post types as well and then WP would be smart enough to detect data in a CPT table and include the needed UI. Then the users could create/manage content types so if they installed a theme that created a custom post type, since it was now in the database, it would stay even if the theme changed. There are many rabbit holes here, but I feel like I’m onto something and would be excited to see WordPress go this direction.
