[Enhance]Preview all windows when hovering over the icon

Preview all windows when hovering over the icon,and if addMac zoom effect when the mouse passes, program start-up effect will be better

Interesting. I was just about to ask how to configure such a feature in dash-to-dock. The title says this is to be an enhancement so I guess it is not available.

I am using v3.28 due to Ubuntu 18.04. For this version, when the mouse pointer hovers over an App icon, and if the App has already opened a window or two, only the name of the App appears. Presently, I use the mouse middle-click button to preview an Apps child window(s). But this isn't efficient as a work flow.

I like to propose that when the mouse pointer hovers over an App icon, the following logic takes place:

1. Check if the App has child windows.
   1a. If it does not, reveal the App name (current default).
   1b. If it does, then preview those child windows which I see a "preview" mode/function already exist that can be implemented.

I am not a js programmer. However, I would like to have a go at it. Can you point me to the filename I should take a look at to implement this proposed logic? Thank you.

[Update]: I think an if-loop check should be made at L416 in dash.js? I did try throwing in an if statement there (see below) but it did not seem to trigger the preview during hover. 😖 Help?

    _hookUpLabel: function(item, appIcon) {
        item.child.connect('notify::hover', Lang.bind(this, function() {
            if (appIcon.actor.hover) {
                // If any window is present, Apps windows will be previewed.
                // If not, Apps label will be shown.
                if (windows.length > 0) {
                    appIcon._windowPreviews();
                } 
                else {
                   this._syncLabel(item, appIcon);
                }
            };
        }));

@sunbearc22 I'm glad that you are interested in this feature.
In fact, there were a lot of discussions before, and also a suspended merge in there #574 , which never could been merged until now and could give you some help.

Unfortunately, the author also has no time to maintain it now #574 (comment).

If you implement it, everyone will cheer and thank you!

Seems a duplicate of #144
