Good Day

I am looking to purchase the Map Forecast API to integrate it in a cloud based application and needed a clarifications / confirmation before i proceed with the purchase:

a. With the Map forecast API, will I be able to set favorites to multiple locations so i can access the required weather data for these favorite locations by clicking on these locations tagged as favorites.

b. Does this allow me to search for additional locations - input via the accepted coordinate format and add them as favorites.

c. Is there a limitation on how many favorites can be added

Appreciate your help in answering the queries. Thank you
