We can’t read the text in the comment bubbles because the bubbles don’t occlude the other stuff in the graph. The only time we can consistently read them is when we’re zoomed-in enough to read the comment in the main part, making the bubbles pointless. Please make them pointful, so to speak.
Or just disable them (new feature in 4.18)
I saw that and am disabling them. It would be nice if there was a global setting that disabled them all. Going around and turning them off for every comment is less than ideal. Plus, with a global setting, two people could look at the same project, one with them there and one with them not.
