Vlad Sorry, my wording was not very clear, I guess 
I wanted to say that using more native controls could lead to alerts looking more like application or system alerts. But the general appearance of the alert âwindowâ allows for the use of native buttons (in my opinion) because the user wouldnât recognise it as a system alert. I wouldnât change the design too much though.
Appleâs intention for this design is to make the user know that the alert comes from the website and not from Safari itself (to avoid scams and so on). Orion should do the same. I think the button is alright though because the alert doesnât look like an application window.
