In order to add content in panels, currently you click add, have to find the right category first and then select what you actually want to add.

#2011814: Add a JS quick filter to the add content modal dialog is a great improvement but it only works after having selected (and found) the right category. I think it would be really nice to speed up the whole add dialog process by adding a global search functionality.

As far as I can see, we are currently using ajax requests to fetch ctools content type plugins individually per category. I wonder if we could load them all and make them searchable.

The same functionality is provided by views add dialog, so for consistency I would propose to implement the same functionality.

Note that we had a similar discussion already for the add dialogs in Drupal 8. xano therefore created https://www.drupal.org/project/plugin_selector
