I will check with our guys, because I see no reason for it to be so slow in opening.
Sooner or later we will kill the "legacy" mode But I understand that that mix in the User Guide can generate a lot of confusion.
It is a transition time and I hope that, also with the new DTouch workspaces, the users will start to think that the Standard mode isn't so limited as they think. I also have the suspect that somebody has abandoned DTouch after the transition to the standard mode: huge error due to poor knowledge of the new standard mode, at least in my opinion.
