Show preview for applications having multiple open windows

Prerequisites

• I have searched open and closed issues for duplicates.

Feature

It would be great to have a preview near the dock when the cursor hovers over an application that has multiple open windows.

Please describe the solution you'd like
Currently, clicking on such an application from the dock opens the most recently used window. Instead, a preview should pop-up giving the user a choice between those multiple windows.

Existing work

I know Zorin and Ubuntu offer this and so does Windows 10:

I like it, but I think it would be better to only show the previews if an user would click on a focused application icon with multiple windows (à la Unity).

I have my windows maximised, so this is a problem for me in that I can't bring up other open windows of the same app without either un-maximising them, or using a keyboard shortcut like Alt-Tab.

Hi.

You can use the mouse wheel or use the right mouse click while this is not implemented.

I think this is obsoleted by #210. Now when you click an app icon that has multiple windows, you'll get a window spread and can select from open windows
