This update improves the Dual mode experience.

・Dual mode now remembers your last layout (side-by-side or vertical
　split) when you return from Single mode — no more resetting your
　view each time you compare.
・Switching between Single and Dual now keeps your layout (side-by-side or vertical split) and playback positions.
・Dual mode: added per-video frame step buttons for each clip, shown when you touch that video's seekbar.(ver1.1.0)

We'd love to hear your feedback. Feel free to reach out from within the app.
