Yeah, our plan is to do camera movements, including curves editor capabilities (ease in/out). This will come in a future update.
Can I ask you to elaborate more on you lip-syncing comment? What exactly did you have in mind?
Are you aware of the X-sheet “annotations” feature in Animation Paper? This is very useful for planning lip-sync. You have your dialogue sound track loaded, you can see the waveform right there in the X-sheet, and next to it, in the annotations column, you can write out the dialogue downwards across the frames (by scribbling it by hand), include notes, timing charts, phonemes and even draw mouth shapes at the points in time you want them to hit.
