[Ayatana] More visible already run application (inside shortcuts)

[Bartosz <gang65@xxxxxxxxxxxxxx>]

Hi.

I would like to increase visibility of already runed application in launcher.
I have a lot of shortcuts and in the first view I don't know which
application is already opened.
On my small screen arrows on the left side is not good visible.

What do you think about display "round_corner_54x54.png" graphic only
when the application is already runned?
I have already created mockup and it looks promising.

I would like to implement this feature to show how it works in practice.
The "round_corner_54x54.png" image is displayed in LauncherItem.qml
file, and tileBackground item.
How I could display this image only for already run application?
How I should change Repeater to handle this?

Thanks in advance
Bartosz
