Hi there, I’m currently designing Hangul using Smart components.
And managing lots of layers at once, there’s a difficulty that I have to click layer’s eye button separately. It would be nice If that I can turn on/off multuple layers visibilty at once:)

Added a “Visible” item to the context menu. So you can select several layers and set visibility from the context menu.
