Saving Favourites in the App

I am a new member and still finding my way around but I have been reading a lot of posts about how you can't save a Favourite site on the web site but you can on the App. They don't sync but from other posts I have read, the IT doesn't seem to be the best in general! Anyway, I am using browser favourites on my laptop to save locations in a separate folder, not ideal but it works, but I have not been able to locate a Save button in the App. Could someone direct me to it please?

Thanks all :-)
