There is one more adjust, new commit.
When i remove dangling image, the fullTag is used to remove the image, or the RepoDigests when it's end with ':none'.
Some cases the digest end with '@none' and this cause an error (bellow).

So, i propose check digest end and use the image ID when digest end with '@none'

@jnsjunior thank you for your contribution, much appreciated!

I think adding the ability to show dangling images makes a lot of sense; I am just wondering if a configuration setting is the best way to enable it. An alternative could be to add an enable/disable button to the Images pane in the Docker explorer (next to the existing "Prune" command, see screenshot below). This would be more accessible/discoverable... 🤔

Also @BigMorty @philliphoff please share your thoughts.

@karolz-ms yes i agree with your opinion.
i will try to implement this function using a enable/disable button on the panel.

Looks great, just a couple minor suggestions.

We are super grateful for this change and for following up on the suggestion to make it a command! 🤗
