Thanks for the proposal. Before accepting, two small requests:

• Could you add an overloaded function without the timeout to keep backwards compatibility?
• Can you update the docs in docs/wifi-manager.md accordingly?

Doesn't the default param value suffice? It already defaults to the same default as the WiFi package.

Yes you are right, sorry I overlooked that :). Thanks!
