I was going to post about one I have been wanting and needing for years, that I was promised a couple of years ago, but just double checked before posting, and I see that there's finally a (beta) app for it in the Google Play Store. Hopefully it will work out, because it's been difficult to be productive without that particular app. Is there an app you've been yearning for, but it doesn't exist? What is it, and what would it do? Maybe someone will read it here and create it.
