It'd be great if this was supported for comment text as well for the "When comment added" trigger.

This would be helpful in processing incoming work orders we receive from customers by system generated email because we could automatically set priority based on priority text in email.

For our organization, a Text parsing feature makes the difference between Clickup being a viable reporting tool and... not. Please implement!!!

I would like the ability to also trigger on subject line of email

Yes please!!! "Text Contains / Doesn't Contain" at the very least, and yes, RegEx would be amazing!!

this wold be a game changer, specially if expanded to attatchments throu OCR, just like filterize does in evernote. Basicaly, just copy filterize to clickup and youll have a super powerfull automation service. I would easly pay extra money just for that.
