I'm finding more and more that I am spending time with the dependency graph as a feedback device, to ensure that I am not creating cross-body links and other problems with my geometry. I've noticed that when I have 6 or 8 bodies or more, each with its own history of features and operations, the screen must be scrolled to see the whole picture.
The wiki page: https://www.freecadweb.org/wiki/Std_DependencyGraph
shows (I guess) old screenshots of the dependency graph, so my first suggestion is that we update those pics. I'd be happy to take some screenshots, I'm currently using FreeCAD 0.18 daily on ubuntu 18.10.
Second suggestion is that we update the wiki text where it says "Use the horizontal slider at the bottom of the screen to pan the view sideways." This seems to be incomplete, because after trying various things, I was able to use ctrl and alt along with the mousewheel, to scroll in the X and Y axes.
Third suggestion is to make dependency graph panning/scrolling more comfortable. I suggest that we map the scrolling action of the dependency graph to the panning actions of the 3D and 2D views. In my case, using Gesture Mode, that would mean right-click scrolling. Going back and forth between sketches, 3D views, and the dependency graph, it's very jarring to have to remap my mind to a different scrolling mechanism for each view. What do you think?
