You gave me a feedback, and I give you a new update, which fixes a number of bugs found in previous version:
• implemented undo the last action for the corkboard;
• added context menu for the connections between cards and for notes;
• fixed a bug with the appearance of the card description in the script text;
• windows of adding card now look good even on small screens;
• by pressing F5, or clicking on the appropriate icon on the toolbar you can go to full-screen mode for working with corkboard;
• now the parameters of arranging cards are saved between sessions.
Who has already had time to try - share your feelings on the new tool !? :)
