The gallery shows a "Thumbnail" (a small image) for each master puzzle. If you have started games based on that puzzle, these are also shown next to it, at its right. The master puzzles show the image and for saved games it shows a snapshot of the screen the last time you played it. Depending on the visualization mode (see Visual display below) it displays additional information.
To open one of the puzzles or games in progress just double click its thumbnail. If you open a master puzzle the program will show the panel for starting a new puzzle where you can choose all the possible variations on that puzzle.
Right click on a thumbnail to open a pop-up menu exposing some self-explained actions to do with that puzzle.
Below the thumbnails there are some options to choose what type of thumbnails must be displayed. For example, if you uncheck Originals , the list will not show any master puzzle (the ones you open to start a new game), but only thumbnails corresponding to games in progress.
In games in progress, if you have set a player's name, you can select that name in the list of players (under the heading Player ). The window will show only the saved games belonging to that player in the current folder.
It's also possible to reopen finished (100% completed) games. Initially Completed is unchecked, but you can check it to make them appear in the list.
The puzzles are initially sorted showing fist the ones with incomplete games followed by the rest ordered by title. In Sort by you can change this and display the puzzles in the shelf sorted by just the title or the time you worked that puzzle, this way you can have the puzzles most recently worked at the top or the bottom of the list.
The options opens a popup menu with:
The option Visual display switches the mode of displaying the thumbnails. Choose what you prefer as this doesn't have any effect on the operation of the program, just the way the thumbnails are displayed. With Visual display the program shows a colored background grouping the master puzzle and its saved games so it's visually easy to see them grouped.
EachPuzzle a row offers an alternate method to display the master puzzles with the saved games, with that option checked each master puzzle will go on the first column and at the right will be saved games based on that puzzle.
