Screenshot show my cursor within a string of bold text. However the toolbar menu button doesn't change to indicate that text-formatting is currently active.
This is particularly a problem if I place my cursor at the *end* of a string of bold/formatted text, as I cannot know at-a-glance, whether the text I'm about to type will come out formatted in some way.
In many other programs/sites (eg. gmail, gdoc), there is always an onscreen indicator (usually the button appears "pressed"), which helps me understand whether text-formatting is active or not.
