Note I originally posted this as 'thumbnail' but then realised I was probably referring to the 'atwork' although they too are thumbnails!
Anyway. More for my wife but I totally agree with her.
The issue we have is easily spotting the selected artwork when scrolling around the screen in a multi-row artwork screen; in our case this is the beautiful Metro theme with 3 rows.
How about having a setting to set the 'magnification size' of the artwork when selected when cursoring around, even an option to put a border around it. Not particularly bothered for complete control of the magnify size but maybe a normal-large-largest (or percentage); so normal being what it is now which I assume is around a 10% size increase. A border could be configurable.
Thumbs up for this product. Purchased.
