It would be useful and convenient for the SaveAs and Save commands to have a simple user option for enabling or disabling file compression directly. Currently the user has to go to the Advanced section of Options to make the change. In SaveAs this could be implemented as an check box option.
Save would then use the option which was selected when the fire was first saved or most recently save using SaveAs. The option could be change using SaveAs.
Rationale - In some instances file compression can result in a 20 times increase in save time compared to no file compression while providing minimal reduction in file size. In other instances the reduction in file size is large enough that the increased save time is worthwhile.
