What are the important apps you think are missing from WP?

[Windows Central Question]

I am a novice developer(soon to be). I am about to venture in the field of apps and I have used WP before as well then switched to Android then to Apple then back to WP. So I have brief idea of what we want from WP. That is quality in apps. Still I wish to know what are your all recommendations if I were to create an app for WP, which should it be? Games/Apps alike are appreciated.

I personally/desperately want Adguard and Sticky Password. Rest comes later. But I want the official apps.

For you, I would like to suggest, a Keepass client, Imgur client or an MS authenticator alternative, that'll allow us to backup our data.
And maybe a skeleton app for forums. You know, if someone requests you for an app for a forum, you'd be able to provide them a good, working, 3rd party client. I know about Tapatalk, but it's slow as hell.
