Perminently delete games from Library
There’s a plethora of reasons to implement this feature but personally I find that having games that I’m never going to play or get the achievements for annoying. It prevents my library from feeling clean and is irritating to see games I’m not going to play with a 0% on the achievements board.
If uninstalled apps would only show in 'Not Installed', it wouldn't be nearly as big an issue. It would still be really odd behavior (especially if free apps still show up there also) but at least the default view wouldn't be an absolute mess. And there is no way to change the default, so we are forced to look at the clutter.
I'm extremely hesitant to ever try out other apps now, knowing that I may not like them and that they then will clutter up the Apps overview. I would think Oculus would prefer if we would try out as many apps as possible instead, generating more feedback, data and money. So this is an absolute no go.
