Using icons in combination with conditional layout in fields

Currently we can only make a field in the application a certain color on the basis of something. It could be showing that a certain field is empty so we make the background yellow or that a price does meet certain requirements so the price has a different font.

Sadly there's no easy way to show to the user what is exactly wrong or going on. We have to resort to help text, pop-up or panel messages, expression fields, extra detail tabs etc.

I would like to see an icon in the application field that shows that something special is going on with that field. It would look a bit like this:

or:

Then when the user hovers over the icon, he or she should see an explanation of why the icon is visible and this should be in their language.

That's why I would like to see this implemented in cohesion with Conditional layout, since that could be the actor showing the icon or not showing it. The icon could be a type of conditional layout the developer can create. Types could then be: info, warning, error, none (maybe even more?) Translations can then be created per conditional layout type in every application language.
