Been there, done that. It bugged me A) how much dross I had coming up and B) how much I had to fiddle in settings to get things quieted down.
Apps that I want notifying me on W10M do so in detail. I think you might be running into overages... I.E. you have so many from an App that it resolves into a number and not the individual entries, or perhaps your settings are not tuned to your needs/desires. I have an IM client for work with multiple channels and I get dozens of individual, chase-able entries every hour because those people just cannot stop posting. The truly important stuff gets lost in a wave of blah blah blah yackety schmackety. It irks me, but I deal with it because job. I have an audible alert for direct pings and the rest I just swipe away as a category. If I swipe a single entry, another fills in from previously unactioned notifications waiting from that app. I still have the counter on my icons to remind me to look on MY time, not the App's time.
I find the settings quite granular.
System > Notifications & Actions > scroll down to the list of apps > tap an app title
- Notifications on or off
- Banners on or off
- Show in Action Center on or off
- Keep private on Lock Screen on or off
- Vibrate on or off
- Notification Sound is selectable
- Number Visible in Action Center (this is for how many detailed entries)
- Set a priority level for that app
There are a LOT of options and customizations for notifications at the OS level and within Apps.
In terms of what shows on the Lock Screen as icons, that is to help you triage and you put the most important items there. To say that everything is equally important might be your choice, but it makes little sense. How can the Twit from your cousin Little Nicky be as important at all times as the email from your boss who sets your work deadlines? You supplement by choosing to make things visible in Action Center, even on Lock Screen and you pull down the window shade and scroll away to your heart's content. If you want every alert/message/notification visible to one and all when your phone is locked, that is your look out. To need 100+ detailed FaceTwit notices on your lock screen baffles me. Why? Because you can? Surely every Social Media notification cannot be urgent, can it? I much prefer to only have to wade through what I need to when my phone is locked and save what I want to for when I have the time to unlock and triage further.
For detail, and selectability of what notifies in which ways and at what locations I don't see W10M lacking at all. The only difference, IMHO, is the nag factor. Android thrives on it, abounds with it and attempts to condition users to crave it. I don't want to be nagged incessantly by my devices. Tell me once and I'll adult it. Tell me twice and it is a waste of my time.
YMMV.
