Hi
I would like to suggest that you have more consistent hotkeys though the program. So for instance adding shift drag to duplicate nodes in the hypershade and node editor like you can with geometry in the viewport.
Also tab for search in viewport like we have been doing in the hypershade and node editor, I know ctrl f was recently added as a hotkey for this, but tab would have made more sense.
Another annoyance is the sliding up and down in value inconsistency, in the channelbox it is the left mouse button, on the fast pop up menu things when you have for instanced extruded you would have to use the middle mouse button to slide through the values, and in the attributes editor there is no option for sliding through the values. So either the mmb or rmb and just stick to it through the program would have been nice:)
Additonally to steal some handy features from max and blender being able to drag attribute values and colors to other attributes would be nice or at least copy paste colors.
