Coming from Toon Boom Harmony 17 Premium here. In Harmony 17, you could select “Current Drawing on Top” and/or the “Light table” options in the Camera View and when you closed the program, they would be enabled the next time you opened it.
We’ve recently swapped to Toon Boom Harmony 20 Premium at work and I can’t seem to get this to work even though this link says those settings should stay enabled.
Other settings stay enabled from launch to launch like having Line Building Mode enabled, but not this one.
