Having a think about this...I dont like the current approach at all.
Given that were going to want way more slots, the idea of graphics, especially at current resolution is
I would personally like to see a similar approach as the Windows 8 Start Screen...a grid of Web2.0 type coloured tiles with reverse contrast text /fonts.
Put the ability to select at least font size, use random colours and if we want to get fancy (you have the time) a user select-able swatch of colour and fonts.
Case in point today, making some definitions for Brainworx Plugins.....they basically all look the same at this size and they are DARK. I think the screenshot approach is a disaster...I need something that I can see easily from a distance..just the name is fine (for me it would be an 18 font)
I realize this is not a Tab we would be in for long periods but...just like web design 'Dont make me think' !
