Hey Hazem,
I was trying to succinct, but let me flesh it out somewhat, although I am sure the wiz kids at Autodesk could improve on it.
With my keynotes, they are just sitting there; all I have to do is click on them and there they are on the sheet, right next to the drawing in which they occur. Details are a little more circumspect. I am suggesting that there be a way to store small common details, maybe as keynotes, so that I can see that I have, say a roof edge, or a junction, and I click on keynotes, or the equivalent, and call it out. Then I can just place the Keynote ( or detail) legend on my sheet and there is a display of equal sized boxes, (down one side) that is not just easier for me but simpler for the trades and the plan checker (I used to own a construction company as well).
To answer you Peter, I have a lot, but there a few that keep coming up.
Having been in construction, I know how easy it is to misinterpret drawings, so I try to draw everything that is not exactly industry standard.
