Some recent changes made to the Canvas Calculator:

• Calculations now use the PPChemAIPIO library (no more Cheshire calls)
• Calculations now optionally include the chemical name
• Allows the user to set which calculations are performed (Settings dialog)
• Lots of bug fixes and performance improvements
• Updated to Draw 2022 (supports 32 and 64 bit Draw)

The canvas calculator fills a small gap between what's possible in BIOVIA Draw and some of the competition.  Draw has its own calculator and it can add that calculated text to the canvas, but the canvas calculator adds the ability to update that calculated text - real time - on the canvas.  Here is is in action:

Late Breaking change: settings dialog now includes an option to apply changes to existing canvas calculations.
