@jasmussen @karmatosed @mtias While working on #7466 I've prepared this table to help us track issues if any.

The main actionable question I have is: should the Duplicate option be available at all times for the Subheading and More blocks?

cc @noisysocks as per #5941 in case you are aware of any other issues/cases

The main actionable question I have is: should the Duplicate option be available at all times for the Subheading and More blocks?

Both blocks have a supports attribute multiple: false, because they should only appear once per post. Also if they are shared bocks, they shouldn't be duplicatable.

[jasmussen]

@nosolosw Solid work here, and I agree with Soean, if the block is not supposed to be used more than once, it would be nice to make the Duplicate menu item disabled in those situations. I wouldn't remove the item, I think it makes more sense that it's disabled, that helps the spatial memory by not shifting menus around.

Got it. So the more directly actionable item would be the contrary to what I've initially proposed: disable the Duplicate option for More and Subheading blocks when they are shared blocks, as to avoid having twice of them in a Gutenberg post. At the moment I can get two by:

• create a More or Subheading block
• click Convert to shared block and save
• at this point, the duplicate option is shown in the options menu; click it to effectively have two of them in a post/page

An alternative could be to prevent them from becoming shared blocks altogether, but I guess there may be use cases where it'd be useful for a Subheading to become a shared block.

I've started working on fixing the Duplicate option bug at #7957

Seems like this issue served its purpose and now we should close it in favor of small actionable issues.
