Thanks, Ashley. I'm familiar with locking items on a slide. I know I wanted a slide order lock feature back in the beginning, so I guess I conflated that intense desire to be able to stop the slides from jumping around at the slightest disturbance with something that actually existed.
It might be useful in future iterations to add a lock next to each slide in story view to prevent slides from being rearranged accidentally. Getting stuff all out of order accidentally is certainly more likely to happen to me than messing up a timeline by deleting or moving something, and we've got locks there. The people I've worked with using this program have voiced similar concerns, so I know it isn't just me. Just a suggestion.
