When right -clicking directly on a part in an assembly, the marking menu comes up. When right clicking in the model browser, it does not. This creates inconsistency when performing actions. A common example is visibility. I turn it off through the model menu on the screen. Then to turn it on again, I have to right click the part in the model browser, but the location of the "visibility" option is in a different place. Disorienting and slow.
I know the menu can be customized, but I'd prefer to leave "visibility" in the menu since I use it a lot & get to it the same way from the model browser.
