Hi Michael, I' m agree with you in this concept. Even if the necessity to place 3 or 4 selected objects on all the other objects is very fondamental.
It's not only a calculated placement according with tecnical parametres, but there is the design also. The job is to develop beautiful objects (overview) and in the same time it's to be bounded from hard tecnical parametres ( sometime with a tollerance of 0,05 mm). Often I'm forced to draw between a web of costruction lines because this way is faster than a continous hide-show-hide-show...
Now with the tool "Lock" all is simpler than before. Better would be a lock that keeps the chosen color ... maybe less intense.

I use a lot of the groupment of objects in order to obtain a clean work.

> but the more that you can break things down into simple things at a time really helps

Is not possible insert a object in more groups now? I could simplify even further my drawing.
Remove whole sections work from the screen. Sections far from where I'm working.

I hope you understand my not very good English.
