Number of tabs displaying in "Thumbnail view" looks not good

[panwac]

In config panel there is option to set "Maximum number of tabs to display" in "Thumbnail view".

I check, that when the number of sides is larger than the limit for tabs, it starts look not good - I don't know, how to say in English...not intuitive?

Eg. I have such tabs: 1, 2, 3, 4, 6 (limit 5)... I understand, that "6" means "last side", but... maybe it will be better to display additional tabs with captions:
<< (go to first page), < (previous number/part of pages), [numbers*], > (next number/part of pages) and >> (go to end of pages)

*Numbers = numbers of sides from current period of listing, eg.: 6, 7, 8, 9, 10
