Can this handle Markdown? I was thinking of using this feature like "For more details go here".

@deecay I'm not sure it should. And you can always add a textbox widget for such thing.

@Arik Yeah that's true, but textbox widget always takes 185px hight (one 'block' of grid, I guess?). It's a bit of an overkill for a oneliner description. Maybe a lower min-height of textbox widget is what I want.

Maybe :)

Hi,

(This is a template message, but I mean every word of it. Also you're welcome to reply)

Thank you for making this contribution. While we couldn't bring it to completion and merge, it's still very much appreciated. 🙇

In the past year the Redash code base gone under massive updates: on the backend we moved to Python 3 & RQ instead of Celery and on the frontend we replaced Angular with React. It's very likely this makes this PR irrelevant without significant changes. :-(

I'm closing this PR now. But if you're still interested in making it happen, let me know and I will reopen.

Thanks.
