New States
as far as I know thats not a feature here yet unfortunately but you can still do it manually if you want to
example:
export your mod from the website, then add the states manually to the mod file that has been exported (Hearts of Iron IV\mod\YOUR_MOD\history\states)
(i made a texas mod using this website but I manually added the new states into the mod's file)
go to your state's text file just like as seen in the image above (Documents\Paradox Interactive\Hearts of Iron IV\mod\YOUR_MOD\history\states)
assign ownership of the STATE to the nation you wish to have it just like how I changed ownership of South Texas (The new state I created) from USA to TEX (as seen in the image above)
And that should be it
(you do these changes after exporting your mod from the website!)

How do i add new created states with the nudge tool to my mod on this website? if it even works.
