I wish for this all of the time!

Stunned this wasn't included in the 2.0 release. This really is RTM's most annoying "feature". The reality is sometimes I only want to dismiss some of my tasks... but I'm not ready to mark them complete (or postpone) them.

Just let me clear the noritifications paritially.

Doing so with a long press on the tasks would be more than sufficient; (Although I could also see an argument for providing a check box and a "dismiss checked" button at the bottom.

Some times I check my tasks because I'm at a certain location. However, some tasks aren't related to my default Check-My-RTM-Locations. Therefore the Reminders are useful.
I would like to dismiss tasks of which I'm certain I'll check on later that day, and keep the exceptional tasks in my Reminders.

Feels like a hole in the design to me, too. I've been irritated by this from the beginning.

I'd also like to dismiss some selectively - ones that I've postoned for a start and won't be doing today. They still show up on the list. And like mikabren, ones I know I'll be doing later, but don't need a reminder sitting there all day for.

+1, would be great to use the approach from the OP or have swipe to remove/an option to remove the reminder in the menu that comes up with press and hold

Reminders are currently useless
