Glad you like the look of it!
It replaces the draggable chrono that Jonz made, but you could have the Jonz orginal too one if you wanted it. But that would be an aesthetic choice only since this chrono still works as a regular chrono too.
Finally the mod does not replace the Flaggen charts in GWX. It doesn't show because the images are from stock SH3, but the flaggen charts are still there in GWX
In fact in the final version there may beadditional charts included
No either/or choices required!
