alertQueue

Returns how many alerts are still waiting to play on your overlays. The alert currently on screen counts too. Use {{alertQueue.total}} for every kind combined, or a per-kind variable for just that kind:

{{alertQueue.follows}}
{{alertQueue.cheers}}
{{alertQueue.superCheers}}
{{alertQueue.subs}}
{{alertQueue.giftSubs}}
{{alertQueue.raids}}
{{alertQueue.tts}}
{{alertQueue.tips}}
{{alertQueue.flowAlerts}}
{{alertQueue.achievements}}
{{alertQueue.shopPurchases}}

For example: Super Cheers in queue: {{alertQueue.superCheers}}.

The count covers every overlay you have open, and only includes alerts one of them will actually play. If you've turned follow alerts off everywhere, follows are never counted. If one overlay plays them and another doesn't, each follow still counts once.

If no open overlay has an alert widget, every count reads 0, because there is nothing to count from yet.
