From bug 959073 comment 45: 1. I select a node I want to be highlighted as a 'reference' node 2. I lock the highlighter on it by clicking on the inspector icon next to the 'element{}' rule 3. I inspect another node somewhere else in the document 4. I make adjustments to the second node while visualizing it's position etc in relation to the first node 5. I now want to 'un-lock' the previously locked highlighter. If the node I locked is not immediately accessible in the inspector view, it can be difficult find the first node, wasting a lot of time. The workaround right now is to lock another node/selector and immediately unlock it. We should consider another way.
