When typing /ggf it throws a .lua error in the core.lua file.

The correction is as follws which opens up GGF options menu directly which starts at line 210:

function GottaGoFaster:ChatCommand(input)
if (string.lower(input) == "debugmode") then
GottaGoFaster.SetDebugMode(nil, (not GottaGoFaster.GetDebugMode(nil)));
elseif (string.lower(input) == "changelog") then
GottaGoFaster.Changelog();
else
local category = Settings.GetCategory("GottaGoFaster"); -- Replace with your actual category name
if category then
Settings.OpenToCategory("GottaGoFaster");
else
print("Category not found.");
end
end
end

Thanks @cheeseslicer for the report and the PR.
Issue fixed with #5 and released v1.4.8
