Many video editor programs such as Final Cut Pro, Camtasia, and Premier Pro have the option to add a marker to the timeline along with a message to remind the user of what to do at that point in time. This feature added to Harmony would make the whole animation process much easier as I can mark reminders on certain points on the timeline on when I want certain things to happen. Not having this feature is frustrating and leads me to do unconventional things to replace the marker feature, such as drawing lines on the sides of illustrations on the frame I would want to add my marker too to remind myself that that is when I would want something to happen.
Let me know if you still need any clarifications, wether it would be on how adding a marker function would work, how it would improve the Harmony process, or anything else. Thank you.
