Text annotation : info on how to render as html... visible in the left down corner

[simonaubertbd]

What's your use case?
Better documentation, stress on some words, text formatting of annotations and settings link to content.

Since I realized in #6641 that we can render text annotation in html, I'm still frustrated how this information is hidden while being so important. This is a really nice feature but I'm pretty sure most of users ignore it.

What's your proposed solution?
To write in the left down corner (I don't know how you name this area) of the widget panel how to render as html, etc

Are there any alternative solutions?

N/A
