It seems like it was only recently that custom notification patterns on a per-app basis was added. I noticed the “notification filters” system, and thought "oh, I can define an arbitrary rule to change the pattern just for specific types of notifications. For example, I use Telegram with a lot of people, including my best friend. I was hoping to define a notification filter in the app that says “vibrate just this notification differently” but to my dismay, notification filters only allow you to block notifications based on content, which is exactly what I don’t want.
So, my main request is to allow defining custom notification patterns instead of filtering out notification content. I imagine this being in the same UI as notification filters, but instead of only blocking, also allow changing the vibration type/sound/behavior.
