Please lock the scroll bar node on the table of contents in Editor Mode. Currently, you have to hover over it, find the EXACT RIGHT SPOT where you can click on it, and only then can you scroll up or down the table of contents or the left side navigation menu. As soon as you move your mouse, the node shrinks back to a thin little line, and it is nearly impossible to grab ahold of. The mouse cursor defaults to the "expand this margin" icon, but will not allow you to select the scroll bar node, which then disappears completely. This issue has persisted as long as I've been using D360, please fix it. Just lock the scroll node so it doesn't resize and remains constant no matter its position
