Not sure what your conclusion is based on tho
but yes I do use them, quite a bit even, however my QH is only set for the night. Keeping that in mind it's kind of easy to see why my qh doesn't mess with my reminders
I learned a long time ago that I wouldn't get the reminder if those two times collided..
In any case, I never said that the feature wouldn't be useful or that it's not needed, what I'm saying is: someone already thought of it, hence the uservoice link, but not enough people upvoted. You can upvote, share the link with others, try to explain to them why this would be needed and why they should give up their votes for it.
Unfortunately I can't do anything else for you mate
