This is on the right track; I’ll take a look. 
But the cynic in me fears it’s just moving the problem to a different window. Not unlike my current fight with proliferation of Slack teams.
With Slack, at least, I’m able to run everything through one IRCcloud client/instance, which aggregates all the notifications & channels in a single tab and/or standalone app. (As opposed to multiple tabs, and/or the Electron model, which is basically tabs rendered vertically with system resources increasing as the team/forum count grows…)
