I opened a Feature Request asking the JUCE team to prioritize vector UI tooling and improvements. There was a recent fix for a bug with the shadower but no communication from the team so far on planned improvements.
I wonder if anyone on the current JUCE team is building UI/products with JUCE (as they were in the past). If not, they probably aren’t experiencing the same day to day friction that we do. IMO the lion’s share of work building anything real is the UI implemention. I’d love to see the JUCE team hire a UX/UI/design team member and dogfood some first class UI implementations so these things can receive the attention and priority they deserve.
