Hi Andy, re: countdown bar - unfortunately it's very difficult to estimate the amount of calculation needed for many operations. Often times CAD calculations work by a kind of iterative refinement approach where an intersection or solution starts out rough and then is refined with additional passes until the result is within tolerance. With this kind of "iterate until within tolerance" operation it's very difficult to estimate before hand how many iterations will be required.

So unfortunately , it's not likely to be technically possible to give the kind of estimate you're looking for on every command. I do want to add a progress bar for file imports though.
