What are white's plans in this Scotch Gambit position? I'll skip the long explanation, but it's not uncommon for me to reach the following position as White out of the opening:

[FEN ""]
1.e4 e5 2.Nf3 Nc6 3.d4 exd4 4.Bc4 Bb4+ 5.c3 dxc3 6.O-O cxb2 Bxb2


(Black to move, most common replies seem to be ...Nf6 and ...f6, though ...Bf8 is also occasionally played)

A number of sources claim that this position is perhaps equal but White has good chances, and in practice I do alright. The problem is that I have trouble coming up with any short-term plans because White has almost completed development but Black's 'neutral' position means that there is little to do tactically and I'm concerned that by making too many passive developing moves (rooks onto open files, etc.) I'm wasting the development advantage that I've spent material to gain. I can see that here White has pressure on f7 and g7, and there is the possibility of tactics after Re1, but I struggle to come up with a concrete short-term plan.

So, in short, what are White's short-/medium-term plans?
you next moves as white will be 7. Ng5..  and you will activate your Queen - dependig of the Blacks move it may be 8.Qf3 or 8.Qd5

Attack the King and use weakness for f7
