Regarding D61: Support units in modal numinput.
The feature in is getting a lot feedback with people confused about it, or finding that it makes their workflow slower due to have to use ctrl - or ctrl x after typing the number, which is not as efficient. We've had a bunch of people reporting this as a bug, and discussion on the forums and mailing lists.
We should consider making it something that you activate, by pressing e.g. the = key so that existing workflows stay the same.
We should make a decision here before the 2.70 release.
