When editing custom cards where no visual editor exists, the card configuration simply drops into Yaml mode with a short note at the bottom that no visual editor is available.
Would it be possible to also show a link to the documentation?
Especially for cards that I don’t use often or have lots of options this would be really helpful …
Remember to vote for your own suggestion.
It sounds like a simple, but good idea, so you have my vote! 
Thanks for the reminder - not really used to this, yet.
We have all been there, so a people help others to avoid making the same mistakes.
But don’t expect a reply from the developers or a quick action.
This might not be added at all or it could come in the next small update without any warnings or mentioning.
Understood - just thought it is better than just keeping it to myself … hoping for the best 
I root for you too
