Feature request: support notifcations in general / across all configured accounts simultaneously

Notifications are the one thing keeping me from using this instead of the browser.

Notifications are sent from a page in browser window based on current logging-in user. So, if we implement notifications across all accounts, two ways to implement came in mind:

1. Make webviews for each accounts and open their page in the webviews. But this would consume much memory
2. Connect to each accounts streams via stream API. This would be more feasible than 1. but it needs some implementation to connect streams.

The 1. is not acceptable. I think 2. would be feasible, but I'm not sure I can spare the time to implement. But your suggestion is reasonable. So I want to remain this issue open and when I have a time to try, I'll be able to look this issue again.
