Actually, I might be wrong but still.
When a user creates the add‑in, they don’t need to install it. The add‑in will still appear under Developed Add‑ins, and from there the user can specify the paths for the test and production environments so that JMP can copy the add‑in to those locations as well.
However, the user must manually create those two folders beforehand.
One thing I’m still unsure about is how updates work in this case. If you include a JSL file in the add‑in and later make changes to that file, will the user receive an update notification based on the updated JSL file included in the add‑in?
Or do we need to unselect the file in the add‑in builder and re‑select it again so that JMP packages the updated version?
