Button components can now be given a specific width and height instead of just being wide enough to fit the caption, giving you more control over your document layout.

MathContainers now have an option that automatically scrolls the container to the bottom if the content grows too large.

ListBoxes now correctly display tooltips.

Many visualizations have been added to the Student:-LinearAlgebra context panel, including CrossProductPlot, EigenPlot, LeastSquaresPlot, LinearSystemPlot, LinearTransformPlot, PlanePlot, ProjectionPlot, and VectorSumPlot.

After performing a self-documenting operation from the context panel, you can now right-click (Control-click, Mac) on the context operation, and from the context menu select the new Copy Command menu item.  This gives you access to the Maple command syntax that performs that task.

Show Command is used to display the command used by a context panel operation while in Document mode. In Maple 2020, the arrow and description now turn grey if the underlying input is edited to indicate that the results may no longer be valid.

It is now possible to launch the Calculus tutors from both the fully stated problem and from the integrand (when the Calculus package is loaded). For example, you can call the Integration Methods Tutor by clicking on $\int x\cdot \sin \left(x\right) \ⅆx$ or $x\cdot \sin \left(x\right)$ and then selecting the tutor from the context panel.

All options from the Show/Hide Contents dialog are now more easily accessible, because they have been moved to a new Show/Hide Contents submenu.

The Arrange Palettes item has been removed from the Palettes submenu.

Alt+S (Control+S, Mac)—Move the focus in the help browser to the search field (note that this is the same key combination used in the worksheet for moving focus to the search box).
