I know that there is already a general wish list for SketchUp so hopefully this is not considered redundant. -DC’s are a broad subject unto themselves.
Be able to organize Options Menu independent of variable names.
Also add check or radio type buttons.
Also to be able to access the entire DC tree structure without having to use the outliner.
Also be able to pull components from the library as needed instead of having to store all possible variations within the DC itself.
Fix the Options menu blanking problem.
Move the Options Menu Up to the first menu when Right clicking a component
Make the Options and attribute menus collapse-able
Make the component menu scroll-able with the mouse wheel
I lack knowledge but I think that it would be handy to be able to access the ruby console from the DC. I have not played with Ruby much but it seems like it would open DC’s to do just about anything.
More interaction with user input would be good -sometimes it would be easier for the user to select a point for example.
