When dimensioning in Paper Space:
1. I would like to be able to change the linetype of the extension lines of dimensions.
2. Being able to put breaks in extension lines
3. Make associative dimensioning work between two viewports with the same scale. (Example: Dimension an angle that is too long for a view port and have to break it into two viewports. The dimensions will not work between viewports)
4. Add buttons for Dimreassociate and Dimregen (Add to pulldown as well) These come in very handy when dimensioning in paperspace and you have to resize or reassociate viewports.
