Feature proposal: being able to iterate on WifiManagerParameters

[fllaca]

I think iterating on WifiManagerParameters could be interesting, in order to make easier the creation of reusable configuration forms, so you could do something like:

JsonObject& json = ...
....
for (int i=0; i<wifimanager.getParametersCount(); i++){
    WiFiManagerParameter parameter = wifimanager.getParameters()[i];
    json[parameter.getId()] = parameter.getValue();
}

// then save the jsonfile into a file
persistJsontoFS(json);

WDYT?

Hmm makes sense

I worry about json parsing and device memory, was looking at one file per perameter model myself. Name the file o/paramname
