This has probably been asked before, and there is probably a good reason it doesn't exist, but PLEASE add FTP access to servers you have access to or allow advanced file management (upload/download files, access folders that aren't ./plugins, etc)
EDIT: I found this on FAQ - https://support.aternos.org/hc…ding-files-and-FTP-access
This is a good reason, but there are many security options out there, and there are most definitely many open-source ones. If not FTP/file upload, at least make an option to link a download link for aternos to download automatically, and only allow links from spigot/bukkit/curseforge/other plugin site.
EDIT 2: I forgot to say this in edit 1, still please allow access to the server root folder so we can modify files like messages.yml, bukkit/paper/spigot.yml, server.properties, etc
