Today we are not able to control the height of the Separator block.

Sometimes we might want the block to be shorter and other times taller. To have less or more space in the design.

Currently this isn't possible but would be good info to query.

The list of AMP Caches is available at https://cdn.ampproject.org/caches.json

This could be pulled in dynamically rather than hard-coding each AMP Cache in \AMP_HTTP::get_amp_cache_hosts():

https://github.com/ampproject/amp-wp/blob/9e049f6554b69e06284ead57d13ef416226a51ec/includes/class-amp-http.php#L191-L239

This is low priority because the list of caches changes infrequently.

The buttons are stacking on top of each other.

Task Description

Work on the eyedropper feature is tracked in #262, and a prototype has been explored in #3007 — but it's still not implemented.

For this reason it's probably best to put the eyedropper behind a feature flag to prevent user confusion. Right now it's just a disabled button in the color picker.
