In the setting page, you can change the following options:

Trace file name (.tzf): set the name of the trace file dedicated to worst stack size. By default this name is the base name of the test with the extension .tzf.
Report Template: change the template of the report generator. By default this template is wssreport.template.
External functions stack size: this is a file that contains the stack size of the external functions (generally functions that are in libraries and used by your application). The format of this file should be in Json, with the extension .tzfe, as follows:
```
[
	     {"name":"printf", "stacksize":4},
	     {"name":"sin", "stacksize":4},
	     {"name":"cos", "stacksize":4},
	     {"name":"tan", "stacksize":4}
]
```
Maximum Size: Enter the maximum stack size in bytes that the application should not exceed.
Security: Enter a percentage of available Stack Size for security.
If you provide the maximum Stack Size allowed and a percentage of available Stack Size for security, the report displays the total Stack Size and verify if this size does not go over the available Stack Size.
