It can edit settings list, Enigma, Neutrino, in their various versions. It comes with FTP, telnet and webif support.
No special features, it only edits lists. It consists of 1 drag-and-drop tree view, has tab navigation, there is transponders editor, xml settings editor, a channel explorer "Channel Book" with channels by categories: services, bouquets, positions, providers, resolution, encryption, A-Z.
May contains some imperfections, I hope to achieve maximum stability with the future 1.0 version. A command-line interface for use without a gui is under development.
Now it runs on Linux, Mac and Windows, even BSD-like (I tried it in FreeBSD).
There is also a demo version (Qt WebAssembly), it runs on normal web browsers, it is limited for a peek before the download: https://ctlcltd.github.io/e2se-wasm-demo/

You can download it from the GitHub repository: https://github.com/ctlcltd/e2-sat-editor, Releases page. Alternatively you can compile it by downloading the free source code.
What else to say... for Windows I think of a portable version, for the other OS normal distribution.
I wrote it in C++ using the Qt toolkit for the gui.
In the past I used DreamboxEDIT , when Wine for macOS support for 32-bit was dropped I threw myself into this adventure.
It's distribuited under the terms of GPLv3, so it's FOSS, and it's free to use for everyone.
Hope you like it
