Apps I would love to see eventually made available on UT:
Video Chat - even a single way to do this would be fantastic - whether it is via eventual support for Telegrams currently alpha video call capabilities being enabled in TELEports - or via Morph support for various web based services, or via WebRTC - whatever gives us a viable option on UT devices that is easiest to implement is all good by me.
Task List with ToDoTxt support - there are a ton of existing task list apps for UT already, but I really would like one that has ToDoTxt support, along with NextCloud syncing support, so that it could be synced to a multitude of cross platform apps, all in a "future proof" format. Info on the ToDoTxt spec is at http://todotxt.org/
Native basic Video Editing app - while there are a number of online web services that can be used for this task, it would be way more efficient and reliable if there was a UT app that could do basic functions like trim, rotate, resize and reformat for videos - especially useful for posting to social media directly from ones mobile device.
Ride share app - it would be very useful for me if there was a UT native app for either Uber or Lyft (the two most popular services for this in the USA). While these services can be hailed via an online web page accessible via Morph, the rest of the experience is definitely not as smooth as what you get on Android and iOS.
Widevine support - it would be nice if there was a Widevine plugin for Morph, allowing it to be used for movie streaming services like Netflix and Hulu. I understand the proprietary DRM nature of this makes it difficult to do this - but given that there are plugins for Linux via Chrome (that is compatible with some of the other Chromium based browsers, as well as Firefox) - perhaps there is some way this could still be implemented.
