I noticed that Synfig doesn’t have lock and/or hide buttons visible next to each layer on the layers panel. I wonder if it’s even a feature in this program. Note that I’m using the latest stable version of Synfig so I don’t know if this is currently in development but I did my research and I can confirm that this is not yet a topic.
There is no hide button, but you can deactivate a layer by clicking on the checkbox, which will hide the layer.
Okay, thanks for answering but still doesn’t fully answer my question.
Lock is only available for Group layers (in their properties).
Okay, I requested there to be a lock for all layer types with the alternative to make it more obvious to do so.
