There is a comment from soft reject that I cannot understand. Does this mean that custom widgets: Facebook widget, social media widget… I need to change it to plugin?
Themes execute the presentation and styling of content while plugins handle content creation and functionality. Anything users will lose upon switching themes is classified as plugin territory. Here are some common examples:
Analytics
SEO options
Forms
Non-design related meta boxes
Resource caching
Dashboard widgets
Custom Post Types
Custom Taxonomies
Shortcodes
Social media “like”, “follow” and “share” buttons
Anything that falls into plugin territory must be added via a custom plugin.
You may use TGM Plugin Activation or equivalent to prompt the user to install the plugin on theme activation, but it cannot be activated without user action.
You can by default leave it blank and in documentation/video to show customer how to add text/social icons there.
For example, this is our latest theme, Park, and on home page there is a text which should be added from customizer.
Also, on our demo margins between posts are -50px (posts are overlapping) but by default there is a space of 100px between. Take a look on video:
