(Make recents useful again on Lollipop)
If your recents (aka overview aka multitask) screen has become completely pointless on your Lollipop-toting device due to it listing every app you ever opened in no particularly useful order, then Recently
may be for you.Recently
uses some root
voodoo to manipulate the recents list, showing you only what (you tell it) you want to see.
You can limit the list of shown apps to only those that are actually running (instead of every app and every document ever), or limit it to apps run within the last X hours. The latter can be handy because Lollipop tends to be fairly aggressive in killing off apps, and you may not want an app you just used to disappear from the list.
Additionally, you can limit the number of apps shown, though it will always show actually running apps.
The app uses virtually no resources (and no wakelocks), and it doesn't actually kill any apps (it only hides apps that weren't running anyway).
