AFAICT you don't use this include.

Done.

Generally we forward declare when possible (it's in chromium style guide). I
think you have this include because of PromotionEntryPoint. You should be able
to forward declare it.

How come you are naming this class as the model? This class doesn't seem like a
model from what I can tell.

[mrefaat, 2017/01/05 00:03:08]

i thought first i'd name it Controller - but after looking through the code for
password manager i found that it's the model that controls the actions of the
password bubble. vasilii@ what do you think ?

[vasilii, 2017/01/05 17:40:20]

For the password manager there are two classes: ManagePasswordsBubbleModel
(contains as much platform independent code for the bubble as possible) and
ManagePasswordsUIController. The latter does the real stuff.

[mrefaat, 2017/01/05 23:54:42]

i changed it to be controller instead

Don't inline the destructor.
