New modes of layout

Version 1.54.0 includes two new modes of layout for landscape orientation and improvements to the way the difficulty of new puzzles is estimated. The changes in detail:

• Landscape (sideways) orientation is now supported on all devices. Previously, landscape orientation was only supported on iPads.
• A new layout setting allows players to choose whether the puzzle should be on the left or right side of screen when playing in landscape orientation. On an iPad, the option of vertical layout is also available, as before.
• The main benefit of the new modes of layout is that the explanation for help does not obscure the puzzle. This makes it possible to study the help explanation and examine the puzzle at the same time. For this reason, players who usually prefer to play a puzzle using vertical layout may still find it useful to rotate the device to landscape orientation in order to study the help.
• When a new puzzle is generated by the built-in puzzle generator, the way the difficulty is estimated has been improved. The difficulty rating now reflects the logical complexity of the puzzle much more accurately.
• Terminology: the introduction and the built-in help now refer to the numbers at the side of a puzzle as "clues" instead of as "sum values".
