Format dict-like text parameters

Text parameters often are python dicts and so it would be nice to have them formatted automatically or at least include an option to do so; this is especially nice when such parameters are included as columns in the experiment list.

Hi @grelade :wave:
Thanks for bringing that up!
You are making a great point here - I’m passing it right away to the product team.

Once we introduce improvements for that I will certainly let you know.
