as you can see, by butons i mean "bigger clickable area" to select the task, and not only the app icon itself. It doesnt have to be anything fancy, just the ability to select the size (width and heigth) and customize with the current options (i.e. border and background color of both active and inactive).
It would come in handy if you add the "window preview" feature.
Is this possible? Or worth to implement it?
