Thanks for making this fix and also adding a way to change some options. It's very nice to see you supporting this product, even though it is free!
Really the last thing I would love to see in this product that would make it perfect is a better system of tracking the outline regions so that using Source Control on these files will be easier. For example if 2 developers are working on the same file, when they check-in, a merge action will be performed in order to merge their two files together. However, it would be difficult to update the SmartOutline associations as they are saved now because they currently rely on line numbers. Not sure how else you would be able to do this, but just an idea in case you'd like to look into it :)
Regardless, thanks for the great work!
