How do I create a settings screen that looks more like the iOS Settings app? * Add option to disable key click. * Haptic feedback option. * Support landscape mode. * Implement ON / flag 44. Windows version: * Press a key with the mouse, then move the mouse outside of the window, then release the mouse button. The key stays pressed; apparently the mouse-up is not handled in this case. * What would it take to fix the Alt-Tab problem? How do you create a "new" style menu bar?

MacDashboard version: * Is it possible to call core_copy() only when the user actually presses Cmd-C, and not every time shell_blitter() is called? The old logic was fine when all Free42 would copy were scalars from the X register, but now that matrices and programs can be copied, that approach really should go. Linux version: * Update low-battery checker to work with /proc/acpi/battery and /sys/class/power_supply. All versions: * Copy and paste should respect flag 28 *and* the host's locale. * Add setting for "always copy full precision" vs. "copy full precision only in ALL mode" (scalars only). * Add a feature for importing and exporting variables from and to CSV files. * Add a feature for importing and exporting programs from and to text files. * Add a feature for previewing and installing skins from the web. * Add link to 42s.pdf in the About box.
