What's NewUser functions and conversions can now access the RPN stack, use bitwise operators, and get and set values on the clipboard.
Added support for hex, octal, and binary user functions and constants.
Added "Rol n" and "Ror n" buttons for rotating by an arbitrary number of bits.
Added an option to stop the buttons from taking clicks when in the background, so clicking on the calculator window to switch to it won't accidentally trigger commands.
Added an option to display the ticker tape at the top of the display.
Added a "Copy" button to the tape window to copy the whole tape to the clipboard.
Added confirmation dialogs when deleting keyboard shortcuts, user functions, conversions, and constants.
Added better error reporting when updating the currency rates.
Fixed a problem entering user constants when the decimal separator is set to something other than a period.
Fixed a problem pasting in some hex, octal, and binary values.
Fixed a problem with notes not being saved with the tape.
Fixed a problem with deleted constant names not being saved with the tape.
