I will just copy my message from K2 forum:

Just bought SIG PRO and it is very nice, fast. Would like just to ask for a new feature.

Can you ad navigator for thumbs ? Like 2 arrows, "next" and "prev".

Tried to fix it byself but all of these navigators use about 50 KB jQuery file, and many others small ones (HTTP requests). And it is not easy to get one to work with SIG PRO.

That way we could use Image gallery under first image in K2 Item and it would be look alike as one compact part. (i´ve seen many websites doing like this)

Point is to have many thumbs not in many rows. And scrolling is something it is not achievable with CSS, only javascript code in SIG.

In CSS3 it is, but not many browsers support it.

Something as at this screenshot, with explanation.

Just wonder about your opinion. Would it be to much time consuming for you to ad it to SIG PRO ?
