I've noticed a few things as well...

If no ftl-project.toml file is found, most commands will panic instead of creating the file the first time. So on a new ftl project without an ftl-project.toml this will fail

ftl config set --inline name value
panic: assignment to entry in nil map

Because the above is setting a global configuration value, the command will also panic if the ftl-project.toml file is empty or doesn't contain BOTH of these. Maybe these should just get automatically created?

[global]
  [global.configuration]

It will also panic as @mistermoe describes above if a unknown module name is used.
