@xannem when we already linked a PR to the issue, let's add the issue to the project instead of adding the PR to the project. Thanks!

[akphi]

Nice work! Just a reminder, we will need to revisit and fix up the padding in Panel... component.

@xannem @akphi as part of this to help users specify post processors, could we provide text examples in text mode. For core ones we can provide them directly and for extensions we leverage getExtraPureGrammarParserElementSnippetSuggestionsGetters
