**Feature summary**:
I want to send an echo notification to **myself**. The most obvious and versatile way would be to make this possible using the API, but JS would work for me as well.
**Use case(s)**:
My userscript cooks things in the background. If/when it has found something, it has to notify the user somehow. mw.notify is just a fleeting notification that can be missed while taking a sip of one's tea. Other solutions generally don't carry over to other sessions/devices/browsers. And, errr, there already //is// a perfectly good notification system and area in place, I just can't use it!
**Benefits**:
Allow userscripts/gadgets/anything that's not an extension to take advantage of echo notifications.
This feature request is different from T58362 as I am requesting only notifications to **self** (which takes away a whole lot of potential abuse factors) and no special page or user interface, just API.
