Provide clarity if a block exists in the language version an editor is working in

We have recently changed to version Optimizely 12.13.1. When creating a new language version of a page using "Duplicate content" it is not clear any longer if a block used on the page (e.g. in the Teaser field) exists in the new language version of the page. Earlier, I think this was made clear by displaying not translated blocks in grey. We use the English block name in all languages, with a suffix for the respective language added. In this way we can track what has been translated. But it would be better if it was made clear visually if a block does not exist in the language you are working on.
