The icon of the button has been discussed a bit in this thread: viewtopic.php?f=15&t=2866
After that, I noticed that we can use dropdown menu instead just using different icons to identify different status of the lock keyframes, here is my mockup:

I think that would be great. I love the new preview and render icons at the top right too!

This is the first time I do mockup in Synfig Studio not a bad tool for UI task, there are some good parts other graphic applications don’t have.
