You can store your work (a story) by clicking the update button.

And you can remove a story by swiping horizontally and rapidly.

Click the "+" button to add an MDP and swipe horizontally and rapidly to remove it.

There are three methods to modify an MDP's time period.

1. Since it is related to an MDP, holding an MDP's dot for a while will pop up a popup for you to set the current time as that MDP's start or end time.

2. Since the left and right arrows aside the PLAY button are related to the start and end time of that MDP, drag them can change those time values.

3. Well, since you can see the values of the time period, intuitively, clicking them to edit them directly.

Once the panel of an MDP appears, clicking its subtitle area can input your subtitle.

By the way, you can use HTML syntax to style your subtitle.

There are four panels:

1. Left panel: It is for all your works and your current work

2. You can enlarge the main screen by hiding dots

3. Right panel: The list of dots' subtitles. Hide them can enlarge the main screen.

4. MDP's screen: It's colored as its dot's color with a lower opacity. You can toggle its position.

Sometimes, you might not set MDPs in order. You can correct it by clicking a button.

Or, you can export your work as a Google spreadsheet file to your Google Drive. Rearrange them directly in that file. Then import this file to get the arrangement you want.
