The idea is, as you can see on the left side of the screen, adding a new SV change tool option. Clicking at that "SV change" icon can make editor immediately generate an inherit timing point at the current position, shown as green lines on the columns. By simply clicking at those green lines and typing floating points such as 0.5, 0.2, 10 into the input boxes, mappers can easily manipulate SV changes without constantly switching between timing setup panel and compose panel.
This is extremely useful for those who want to implement a lof of SV changes as well as those who want to check others SV changes. Any ideas?
