This Crossword grid displays the current crossword. It can be edited, reshaped, filled with words automatically, cleared, and much more. Selecting a word in the grid also selects that word in the Clues panel.
The Clues panel is used to edit the clues of the current crossword. It supports sorting by any column, hiding / showing individual columns, and highlighting complete / incomplete fields (for example, here no clues are filled, so all the Clue fields are highlighted red).
The Scale slide is used to zoom the crossword grid in and out.
The button at its right side lets you adjust the grid size dynamically to fill maximum space when the window is resized. This behavior can be toggled on and off.
This element in the rightmost corner of the Status bar displays the current version of pycrossword. If there is an update available, a notification is shown next to the version. Double-clicking the version launches the app update process.
