I guess those apps confuse (mix up) "ongoing" and "event" notifications. They have different flags, believe it should be possible to tell them apart...
For the record, I contacted the developer of NoLED before, got no response -- while the developer of LightFlow actually fixed it on his side.
What you can do is turn off my app's ongoing notifications, it's in the app's global settings, extended mode (top item), towards the end of the "User interface" section.
I'm going to list some techie things here, just in case someone wants to try forwarding them to NoLED:
1 - The ongoing notifications have Notification.FLAG_ONGOING_EVENT set in their flags
2 - If that's not enough, they also have:
intent.putExtra("org.kman.AquaMail.IGNORE_NOTIFICATION", true);
