I understand what you are trying, to make changing the WP config settings more convenient but I do not think it is possible to change them from a plugin. Constants like WP_DEBUG and DISALLOW_FILE_EDIT are defined in core files, specifically in wp-config.php, according to the Codex and, looking over the source code of this file … Read more

Another advantage would be that transient beneath use cache. If for some reason your will need to install object cache your … Read more
Is there some way to implement a multi-input field that will take as many phrases as the user wants to enter? Yes, there is — you can add an input field where the user will enter a number, which is the number of extra phrases he/she wants to add. But I’d go with a JavaScript/jQuery … Read more

All options are loaded at pageload, because they include not only plugin/theme options, but also WP native stuff, like menus and widgets. Distinguishing between which ones to (not) load based on whether they are needed would take quite some calculations, so the performance issue you refer to doesn’t exist. Now about the extensibility. Let’s take … Read more
If you check the implementation of get_option() you’ll see that in line 168 it calls wp_cache_get() like so: $value = wp_cache_get( $option, ‘options’ ); This means multiple calls to get_option(“style_settings”) within the same PHP execution will be served from cache.
