Feat Req: Auto select first item

[YouveGotMeowxy]

When viewing an image, if you just click "view ocr'd text" you'll get the message saying something along the lines of "select a thumbnail first"; it would save some clicks and frustration if PM auto-selected the first item in the thumbnail list (which often is just 1 in my case anyway) when viewing the item.

This way if it's only 1 item, user won't' have to fist click it; if more than one item, user would have to click a thumb anyway, so if they don't want the 1st one, they can just click whichever else; but if they still wanted the first thumb, it's already selected for them.
