Making connectors more visible in the web model

I try to display the connector arrows graphically in bold. I have also indicated in writing that you can navigate between processes / sub-processes by clicking on the "bold" arrows. Unfortunately, this is overlooked. Is it possible to add an info field with a mouseover that says "please click" or similar?

In addition, the first process step flashes briefly when the connector is clicked. Is it also possible to highlight this again in color? By the time you have oriented yourself in larger swimlanes, the flashing is sometimes already over or is not recognized.
