Recently Flow and Echo added strings with bolded and double quoted UI strings. This double emphasis is a bit too much. I've submitted patch sets to remove the quotes, and leave the bolding, using <strong> instead of the wiki markup triple quote which marks up as <b> to be more internationalisation friendly.
I think I might even be in favour of moving the markup where it strictly applies to parameters from UI string to code. This simplifies the string, and harmonizes the visual design.
