Is it possible to make it to where everytime I clicked the mouse it would pop up with an elevation option. This would be great for taking off wall...

I would like to see if you guys can add in elevations to the linear function. It would be nice to ba able to put in: Top of Wall Bottom of Wall...

Is it possible to trun revised pages on and off and overlay them with the original without having to download them into a different folder?

Would it be possible to put in a text chat function. It would be nice to get a quick message to someone when they are on the same page.
