Added an option to show or hide the currently selected primary click type. (Options > Puzzle > Puzzle Appearance > Show current primary fill type when using mouse)
If you uncheck this option, I recommend changing your mouse input settings so that left click is always "Fill", rather than "Primary Click". That way, you don't inadvertently change what the left mouse button does via the mouse wheel without a visible indication that it happened.
Added an option to show or hide the checkmarks that were recently added next to the titles of completed puzzles in puzzle select screens. (Options > Appearance > Show checkmarks for solved puzzles)
Reduced text margins to allow more space in menus for the new options.
Fixed a bug where the puzzle shown on the solved puzzle screen would display at an incorrect size after changing the resolution.
