Allow the default border around the mobile apps to be changed from the default BLUE color to a custom value.

Please add a global setting ability to allow users to change the default BLUE borders around every form APP to a different default color. 

We know this is the default GoCanvas blue theme, but other competitors allow much better customization of forms to match a company's documentation and branding themes.  Our company's branding is all dark green, it would make our APPs appear to be more customized for our company if I can change to the green matching our branding.   

Although I ultimately chose GoCanvas over your competitors, this was a negative functionality that I had to overlook in my final decision.  Please consider.
