• Tools
• mcgui allows definition of an "external editor", see the configuration menu.
• On Linux we preconfigure for gedit (where we now also provide syntax-highlighting, on macOS and Windows we default to use the OS file-type settings, i.e. whatever you get by double-clicking an instr file.) Use ctrl/meta + shift + e to spawn the editor from mcgui.
• Platforms:
• We still support 64bit Windows 10/11 on Intel, all recent 64bit macOS including 11.0 Big Sur on both Intel and Apple Silicon/M1 processors. Debian-based distros on Intel and Arm, RPM-based distros on Intel. (RPMs are built on/for CentOS and Fedora, you may get varying milage elsewhere.)

We provide x86_64 Debian packages here on GitHub. For other platforms, please refer to:
