We have had a small handful of very vocal users that have wanted this, but when it was on a community poll know one cared and it got hardly any votes. As for it being a single line of code, thats not true at all, it would actually be a major overhaul of the interface and backend code as everything would need to know that its possible to load into a app directly rather than opening a new wheel, so a complete re-structure of Launchbox and Bigbox would be required. Hence it hasnt been implemented as so few users care about having it so it is not worth the dev time/money currently.
