This addon displays many useful things, like the current time, your loot spec or your equipped gears repair status. It originated from a quite practical WeakAura, which I got shared from a guild member. I was never able to track down the 100% original WeakAura because there are simply too many versions of this WeakAura floating around on Wago.
That being said I want full disclosure that, even though I fixed some of the broken API calls when they were changed at the start of Shadowlands, I have copied much of the logic code from said WeakAura and is not actually authored by me.
This addon is officially available from its Wago Addons page, as well as through GitHub releases. Furthermore you can download the source code directly from the GitHub repository.
I've chosen these platforms because they are the ones I personally use, and at this time I don't see a reason to create releases for other platforms, as there is no demand. Nonetheless, I understand some people also use WowInterface or CurseForge, so if you'd like me to create releases on any other addon platform please create an issue on GitHub and I'll look into it.
You are very welcome to contribute to this repository by cloning it and once you've made changes opening a pull request. I'll take a look at those changes as soon as I am able to.
