The Nav Bar also has a popup menu. Right clicking shows a menu with commands for undoing and redoing moves. Saving and returning to saved positions and more. All commands are described here.
The lower thin green bar represents the overall position among the moves made. The white rectangle selects the part that is showed in the upper bar. The lower bar is only shown when it is needed (i.e. when enough moves has been made).
The tick marks on the top, each represents a move. The longer white mark is a saved position. These can be set during the play and later easily returned to.
Clicking the upper part with the thicker green bar, plays the game to that position. Clicking the lower part has a similar function. First the white rectangle is moved to include the point clicked and then the game autoplays to the indicated position.
Import moves by selecting and copying from any source. Click the "Import Moves" in the menu (Ctrl-I). This will execute the moves from the clipboard, just as if they where done manually. Note that moves after the current position will be replaced by the imported ones.
If you get to a point where there are several ways to continue, clone the tab and choose one way to proceed. Later return to the previous tab to try another aproach.
When creating new levels in the editor mode, you can edit in one tab and play the new level in another tab.
The state of all tabs are automatically saved when exiting the game. The following are saved for each tab: The level identity, the moves made, skin name and size, Edit or Play mode. Number of tabs is maximized to 10.
