How do I lock layers?
Just like objects, layers can be manipulated as well. However is this used for making designing easier and not for designing itself.
When you can work with different layers above of eachother selecting the right objects can be a quite tedious task. In Figma you can lock layers to make designing easier.
When you select a layer in the layer pane, a lock and eye will appear. when you click the lock (it will close) the layer is locked and can't be selected. You can also do this by right-clicking the object and select "Lock/Unlock."
To unlock, click the lock again (it will open) or right-click and select "Lock/Unlock."
