Changes

• Renamed "Suspend Enable" setting to "Sleep Enable" to make its purpose more clear. As a reminder, this option controls whether all i41CX+ operations are suspended while the device is inactive (i.e. screen locked) to minimize battery drain. This option is useful for users that leave i41CX+ running (open) for prolonged periods of time. Conversely, disabling this option allows programs to run, alarms to go off, etc. even after the device/screen becomes inactive at the expense of reduced battery life.• Implemented 2 new functions: – COPYTXT: Copy the contents of the specified extended memory text file into the clipboard. – PASTTXT: Paste clipboard contents to specified extended memory file.• Added support for using the traditional HP-41 "bbb.eee" format to specify a range of registers to copy or mail with the COPYR and MAILREG functions. To specify a range of registers, place the string "b.e" without the quotes in the Alpha register, and the bbb.eee range in the X register, and then execute the COPYR or MAILREG function.• Added "Import from clipboard…" item to Overlay picker. This provides an alternative way to import overlays (e.g. from an email) in addition to downloading from a URL.• Added support for extended memory data files. All the operations supported for other data types are supported. Extended memory data files are associated with the new "DATA" data type image in the Load Data and Save Data pickers and are recognized by a .DAT file extension when downloading from a URL.• Added support for extended memory program files. Extended program files are distinguished from regular program items in the Save Data picker by the blue "PROG" label (regular ones have a white "PROG" label) and are listed following any text and data files. Extended programs can be emailed or saved just like regular programs. The Load Data picker now shows all program files under both white and blue "PROG" labels. If a program file is selected from the white "PROG" label picker, it is loaded into main memory as before. If, on the other hand, a program file is selected from the blue "PROG" label picker, the program file is loaded into extended memory. In effect, the white and blue Load Data "PROG" pickers select the destination of the program file.• Added "Bauhaus Smooth" to the "LCD Display" global setting.• Added 3 new skins: "Aluminum", "La Pomme", and "La Pomme Mies". While it is a very non-traditional looking skin, the "Aluminum" skin is particularly well suited for use under bright daylight conditions. The "La Pomme" skins have large buttons and an uncluttered display area. We recommend setting the "LCD Display" global setting to "Bauhaus" or "Bauhaus Smooth" when using these new skins.• Added "Quick Start" option to the global settings. Depending on the device model and system load, enabling this option reduces the app launch time by 25-50%. Note that while this option is enabled, the app ignores the "Key Click Sound Type", printer "Volume Control", and "Ignore Mute Switch" global option settings. These options are forced to "System", OFF, and OFF, respectively, while "Quick Start" is enabled.• Added new SandMath overlay and updated 41Z overlays to the i41CX+ overlay repository at http://alsoftiphone.com/i41CXplus/Overlays/.• Bug fixes, internal code optimizations, and improved exception handling.
