Not sure if this was intentional or a bug, but I used to use the scene slider on the timeline ALL THE TIME to adjust automatic multicam scenes. I'd frequently run into situations where it would create the scene at the very start of a word, or sometimes after someone has already started talking, and would need to manually shift the start or end of a scene slightly to allow for a more natural switch.
With the new timeline update, that slider is either super tiny and easy to miss (very rare), or simply not available on the timeline editor at all (almost all the time). You can adjust the scenes on the transcript, but it runs into the same "start of the word and nothing else" issue and can't be finely tuned beyond that.
Please, for the love of not needing to do 5 separate functions to work around this issue, make the scene slider bigger and always available at scene markers in the timeline.
