Sorry to hear that.
We have been a one sheet one file structure for a while.
Wow an insert flash button. Have no idea what the teletype button does.
Helios is pretty cool. Don't like how to get to P.M.'s but small thing.
Yes, I think the multiple tabs thing would be more a problem in an environment with a lot of users working on each project. We very seldom have more than one person at a time pushing on a single project. Even when all three of us join forces, breaking things up into street, storm, sewer, grading, plat keeps everyone of all of the other's toes. I will try to remember to give it a try, but some of our projects are so small it may be more cumbersome. The last full project out was so small, I kept the whole thing in the model with zero xrefs.
