Hi, Here I am again with Mapiah. Now I believe we have an already usable version of Mapiah. You can find it at https://github.com/rsevero/mapiah Currently there is a Linux flatpak and a web release: - Linux: flatpak install io.github.rsevero.mapiah; flatpak run io.github.rsevero.mapiah - Web: https://mapiah.org/webapp If someone is interested in creating a Windows, MacOS or another flavor of Linux package and want help, please contact me. Some interesting characteristics of Mapiah: - Visually distinguish all point, line, and area types supported by Therion. - Graphical interface for editing all supported options of points, lines, and areas supported by Therion. - Multiple mouse and keyboard pan and zoom options. - On save, original file lines are only changed if an actual edit modified them, which facilitates version control management. - Uses Therion as the source of truth regarding supported features; i.e., if Therion supports it, Mapiah should support it as well. - As a secondary effect, tries to update and detail the Therion Book so it better reflects Therion features. - Equivalent versions for Linux, Windows, MacOS, and web. - Unlimited undo/redo. - Redos available after some undos and new actions merged in the undo queue. Please try it and let me know what you think about it. Regards, Rodrigo
