My approach is different.
I save the ipa file first in my project folder and then upload to the store. Therefore, is not useful for me the file dialog.
Besides, why should I always assign a file name when the ID knows the name?
I think you have a point Filipo because I'm also following the same approach to test my app in my device as an ipa using Appandora before I distribute it to the 100 devices for ad-hoc distribution. I had a crash in my app without debug showing anything so I need to be extremely sure that my app works before I distribute ad-hoc. I dont want a nice surprise of the app being rejected in iStore without ironing out the issues. I'm currently still trying to debug it and I think this option would be advantageous.
As an addition, I would recommend a progress bar added to show the progress of the download because for countries like mine, where the internet speeds are near to horrific at times, not knowing what the IDE is doing due to now showing what its doing leaves me
