In the three settings tabs there is the 'Save' button. It is used to save changes to the current configuration and the is way into the 'Save As' function used to make a new configuration. Personally, 95% of the time I just want to save a change to the current configuration, but need to make two clicks to do that because each time we click 'Save' we must choose to which configuration we wish to apply the change. I'd rather make one click.
I would suggest separate 'Save' and 'Save as' buttons to reduce mouse clicks when we just want to save a change to the current configuration. The 'Save' button would save the changes to the current configuration (one click), and the 'Save As' button would enable the creation of a new configuration (two clicks). The new 'Save As' button would function precisely as the current 'Save' button.
Does this seem like a decent idea?
