Hello my friend. Regarding the DayZ Server Manager, you have to enter your Steam username and password—that’s the only way it works, at least as far as I know. It would be amazing if you created a tool like that!
Have you ever thought about making a server manager like DayZ Server Manager that downloads mods directly through Steam? I loved your panel; if there was an option in that format I mentioned, it would be great. The community has few options for use. I honestly didn't like the new CFTools manager.
