I tried this online program but found it was very limited for external components like optoisolators. I wrote to those managing the site but was told they had no plans to add more components.

This type of thing typically happens when a company like AutoCAD, which is strictly "for profit" picks up something like as a way to draw people into their family of for profit products. The simulator is great, but as you say limited components and no way for anyone else to create/add components. Would really like to see them provide the later capability if they don't plan to put any additional work into components themselves.
