Correct me if I am wrong, but I do not see a way to change the width of the folding margin. It also appears that `fold.on.open` does not work in Geany. Could a feature be added so that users have access to setting the properties that would normally be seen in a `SciTEGlobal.properties` file? For instance, I am needing to change `fold.margin.width=24` and `fold.on.open=1`.
