Usability DetailViewer

[kroegerc]

For optimal handling of the planned DetailViewer, it would be great to

• be able to de-/activate it with a Keyboard-Shortcut OR a button in the taskbar (you could use the "magnify" material design icon available at https://materialdesignicons.com/ ).
• toggle between the main-viewer and the detail-viewer via keyboard shortcut
• highlight the frame around the detail-viewer whenever it is active (toggled) and display a pointer to the original location in the main-viewer (as displayed in green ... maybe not the best choice in color ;-) ) as displayed below. This pointer would need to adust its location whenever the user navigates within the detail-viewer.

Happy coding :-) Christine
