Android: Google has updated its note-taking app Keep with a couple of nifty new features. The most useful is shared lists, so now you can, for example, create a list for your household and everyone can mark items done in real time.
The update also allows you to search your notes by colour. Keep has allowed you to colour-code notes since the start, but that's been a mostly cosmetic feature until now. With the ability to search by colour, you can assign a particular note a specific category and then pull up only the relevant ones when you need them.
