[Feature Request] Icon on toolbar indicates currently used formatting

[athanro]

If text is bold, mark bold icon on toolbar - change it's background or make button pressed.
This is applies the same for all icons on toolbar, especially bold, h1, h2, h3

It would be great to be able to position the cursor on some rich text and see what formatting has been applied to that text. Perhaps more than just the bold icon indicating state, but the bottom status line indicating the bold/header and the font type/size.
