I just noticed that my HeliBoard icon in the list of apps has a green dot to the left of the name below the icon itself. I have no idea what it means -- it seems to be different form the privacy green dot you may get in the top notification area.
Also, I've noticed that when I type, not only do some things get underlined in red (I think it's for misspelling), but also in blue. Any idea what that means?
Thank you
Red underline is indeed for spelling, and blue underline is like a grammatical error - sometimes I find that if I tap the words it will suggest changing the wording to include an "at" or some other word that I left out.
Don't know about the green dot, though, sorry!
