I've been beta-testing Broomstick, Harv, and v 0.9 (to which you linked), in my opinion, anyhow, shouldn't have been released (particularly, prior to my reporting the results of my testing).
(Have you actually been able to hide the listed apps' icons? I'm running NoSleepHelper and DNSCrypt, but the only item I'm offered for hiding is Spotlight.)
Edit: I don't want to get involved with details...just want to know if you're experience is the same as mine.
My experience has been quite positive. I easily & successfully hid Boom and Dimmer with no (known) adverse consequence.
I have not yet tried to reorder the login sequence.
