The big red plus?
When in the forum, I see a big red circle with a plus sign in it in the lower right corner of my screen. I have no idea what it does and it does not have a tool tip.
Right now, there are two of them (never saw that before).
What does it do and can a tool tip be added?
Do you mean this one ?
