Comment 3 for bug 1501128

I just tried installing terminator-gtk3 again, this time the latest r1637. I can trigger the hidden/visible state perfectly now.

A small note: unlike terminator-gtk2, when I make the window visible again, it doesn't automatically bring it to the front. I looked in Preferences > Behaviour > Always on top, but that doesn't do anything. I'm using KDE Plasma 5, and fortunately I can emulate the previous behaviour with Window Rules, so it's not a problem for me personally.
