CH5 is still too new to rely on, even those of us who did training on it, and are trying to deep dive in it, most likely still aren't deploying CH5 projects in production yet (I may be wrong, but I'm guessing if there are, they are outliers). For most of us, getting fixes for loosing the web based version of Smart Graphics is a higher priority.
Since we're half way through Nov already, I'm going to go out on a limb, and say 'probably not'.
Does anyone have a sense of whether HTML5-based browser control is really going to happen in 2020?
