There's no reason upcoming events shouldn't also be visible in the month widget. These are more closely related to each other than month and "today". At least having the option to show upcoming events should be added. Having 2 different widgets for this purpose is inefficient and wasteful.
I agree with this also, the events section should show the next 3 to 4 days of events or allow the selection of days on the months side to show events on the right side.
