Why has Discord gone this long, without a Notification Log/Feed?

I apologize for having to ask this in such a manner, but I just can't wrap my head, on whether or not the developers of Discord actually use Discord, on a day to day basis. If they do, and they have more than one, two, maybe a dozen different servers, and assuming actual friendships and acquaintances met on these servers, and voice chat groups, and gaming servers... and the many, many channels within each of these servers in which they may want to participate...

...how they can feel, they have had meaningful, effective interaction with any of them, even from a sheer lurking perspective.... how in the hell, is all this data, which Discord is managing, all this media they are storing, all these calls, and messages, being considered efficiently utilized when you can receive, over three dozen notifications within a classroom period, and there is literally no way to review them, in the slightest? None.

No history feed showing when a DM was received, or image sent to a channel you love that has been quiet for a bit, and will be for days because 40 other messages have arrived and you might see a third of them, and if you don't review them the moment you address them, they're lost in the ether. What is the point, of flashing notifications on my desktop, if I'm playing a match, in this gaming chat software, and when i'm done with my match, I can't look at what the hell just flashed on my screen 7m ago, or the other dozen notifications I briefly surmised I would have loved to participate in, if I knew where it occurred, who initiated it, and have a path to get to it, waiting for me.

You went through the trouble, and the development effort to push that message to me. It should be retained, and made use of. You successfully notified us! That took time and programming, and long nights.... We can tell. It can't sit well with you, knowing you got the job done, and I can't even prove it ever happened. Because it's gone, there's no log, no feed. It happened, but it's not here anymore. I have to now review dozens of individual channels, and message bubbles, to find it...

This is such a common issue, that the only real answer for most is focusing on one or two servers, and pretty much barring DM entirely with most people. There simply is no way to have a meaningful and productive level of engagement on this platform, something achievable on pretty much everything from php.bb forums, to Skype. I don't even visit Tumblr, and I know every single thing meant for me to see is waiting for me on any device...

...but the app I'm spending my time on, can't make sure people can reach each other, and respond to ... to it... like, these are your notifications you're pushing to me.

Why is this not a priority for an app with THIS much multi-tasking layers of interaction? I see this asked for constantly. It's not just a cute feature, guys, relationships, professional, social and aspirational, believe in this app, and there's no way I can imagine this hasn't affected nearly every single one of us daily.

It's hard enough to keep up with each other,  it's painful knowing some of the conversations that have passed me by, that I was there for without knowing it. ...  thank you.
