i get what you’re saying and it does seem as if some of the toolbar (containing the sidebar switches/ ortho-snap-history-etc) could be consolidated with the window frame options (viewport controls)…
that said, i’m not entirely sure if there are other options which may go there in the future but if so, it’s probably wise to leave some space for future additions.
–anyway… about presenting to clients… i had a meeting on monday and set up rhino like this.
that’s my entire laptop screen… no crops (though scaled down for posting here)
• full screen
• right-click on toolbar → hide toolbar
• i toggle the sidebars via screen edges (_ToggleRightSidebar _ToggleLeftSidebar)
• my osnaps are toggled with a 3finger downswipe (_ToggleOsnapPanelUnderCursor)
you can also toggle and individual layers panel and properties panel if desired…
to me, the presentation possibilities with rhino are pretty excellent as you can get rid of almost everything except the viewport while still having fingertip access to all of if.
