How Can I Add the “Insert From URL” Tab to a Custom 3.5 Media Uploader?

I’ve been digging through the source code for a similar reason; I’d like to add the “Attachment Display Settings” to the default “select” frame.

Limit number of Widgets in Sidebars

I solved this in Javascript. If you want to completely prevent it you should also do it server-side, because you can edit the widgets with Javascript disabled (try it out!).

Great News, I’ve fixed it. Apologies for missing your gist in my initial comment and giving you an answer that you had already implemented. That’ll teach me to answer on my phone while on a train!

WordPress 3.8 – Dashboard 1 Column Screen Options

Another solution is to add the columns setting back to the settings. function wpse126301_dashboard_columns() { add_screen_option( ‘layout_columns’, array( ‘max’ => 2, ‘default’ => 1 ) ); } add_action( ‘admin_head-index.php’, ‘wpse126301_dashboard_columns’ ); There is a related Trac ticket: #26354

Stay with me, there is a goody hidden deep down … How WordPress widgets are stored The list of widget is stored in an option named ‘sidebars_widgets’.

Between functions.php (theme), widgets, and plugins, which is loaded first?

The plugins are loaded right before theme (yes, I’ve been looking for excuse to use this): However it is wrong to think about either as point of code execution. For most cases everything should be hooked and executed no earlier than init hook. According to Codex widget registration with register_widget() should be hooked to widget_init. … Read more
