e.g.
* I want to be able to have syncthing pull down my keepass database and have keepass2android open the current version in launch without having to navigate a file picker every time.
* I want to use my browser to download rpg rulebooks from drivethrurpg then open them in my PDF viewer without either of those two having to specifically integrate with each other. It would then be nice if that pdf reader could display a list of recent files on launch rather than reopen a picker.
They're mostly my gripes with Android 10's lockdown but iOS doesn't even want the filesystem exposed. I won't deny there's security advantages to this model, but it should have an out as it just encourages your app to own your data and only use it in ways they foresaw rather than giving control to users.
