Description - Add an icon/indicator to let you know that a scenario save is still in progress. There is only a text notification once a save is completed.
Why is this feature important to you - Sometimes when you click the 'Save' icon it takes quite a long time to save. After a while you wonder whether the save has completed yet or not. There is no indicator currently to show if it is still in progress. Sometimes you click save again and then the first save finishes and you later get another save confirmation. Alternatively you might close the browser before the save completed and then you lose your edits.
How would you like the feature to work - Either change the colour of the Save icon to indicate that it is pending, or add a spinning circle on top of it, or even a progress bar. Something to show that it is still working on it.
