I have tested both these new features during the new Level 2 course while triggering the robot from the assistant. Works great on linux (Kubuntu 20.4), on Windows another attribute for the dialog box could be wonderful: developer defined “Dialog Window Size”
As you see the windows sometime do not size automatically, to show the text or the button. If the robot is configured to use the failure dialog to give the user to retry again then the Close button needs to be pressed but since the window size is automatic the user may press exit button thereby terminating the robot execution. This is just an example case, not so critical in this case, but the ability to set window size or a way to ensure that all elements in the dialog box are visible is my improvement suggestion.
Thank you again!
