I have created a spreadsheet which may be useful when creating a vehicle mod so you can keep track of the things that are already in place and what still needs to be done.
There are checkboxes in the leftmost column to keep track of the stuff that is done in your LFS Editor. The "Progress" indicator in the header shows how many of the items are done.
You should be able to create a copy to your Google Drive folder by choosing File - Make a copy.
Let me know if there's something missing or something could be improved
