National Instruments has a feature request feature website called Idea Exchange (IE). For several of their products (DIAdem and DAQ hardware amongst others) there is a place where you can post your ideas of improvement of that specific product. However the most popular version of that Exchange is the LabVIEW Idea Exchange. There are numerous ideas (currently more than 100) and recently the 50.000th vote (kudo) was given on that site. There's a blog about the Idea Exchange from a development and marketing point of view.
With the release of LabVIEW 2010, NI made a video with the authors of some of the ideas implemented in 2010:
Personally I think NI only picked 'easy' ideas for LV2010, but if you look at the items labelled 'in beta' it gives you a good idea of what's to come in LV2011. And those are promising!
In a series of blog-posts I would like to discuss some of (my) ideas that I think should deserve more kudos because they are valid for the LabVIEW programming language, so stay posted!
