Prototype real size

In the prototype preview section, 
im my opinion, there’s too many phones ultra precise sizes, we won’t use because we build responsive.
And there’s missing all the most common standard screen size that we really need :
1280x720,
1366x786,
1440x900,
2560​​​​​​​x1440

Also, i’d like an option to add the “windows task bar”at the bottom (48px) and the “biggest Browser interface” at the top (120px) so it can preview the real life size of our prototypes.

thanks
