I know that this is probably on the list or I am not doing something correct here but here goes.
From what I can gather to change a numeric property value the user clicks on the value with the mouse and the property title will change from gray to green indicating focus. The user then drags the mouse left (for lower values) or right (for greater values). This is similar in Blender (since we are talking open source). But what would be nice is the ability to be able to enter a number via the number pad. How you accomplish this I will leave up to you the programmers.
Thanks again I like what's going on please don't give up this project.

I don't know about Johann's plans, but it sure is in my mental list. Thanks for reminding. :)
