How to show/hide regions without reloading?

[egorksv]

Hi,

We have a massive track (think 6-hours stream) with 400-500 AI-generated regions. When it comes to manual editing and adjusting in post-processing, there is a need to quickly show/hide all regions - is there a way to do that without clearing and re-creating all regions?

I've seen some thing about "opaque regions" in other threads but couldn't find any specifics on that.

Many thanks!

addRegion returns a region object which you can later remove with region.remove().
