This is the repository to install the unofficial AppImage for wxMEdit.
Look in releases, install the appimage then:
chmod +x wxMEdit-3.1_FIX1-2.AppImage
The AppImage is now ready to use!
The software, wxMEdit, was built in Ubuntu 16.04 (xenial) in a virtulized environement. Please use a modern amd64 linux distribution before trying. I'm using Fedora 35 for reference.
