Instead of using the Bookmarks option of the K3 browser (with only 8 or 11 links per page, and new bookmarks always added at the end of the list), it's probably a better idea to create a webpage (with subpages) on your own website, with as many bookmarks as you like.
And a link to that webpage as the first entry in the Bookmark option of your K3 browser.
Advantages:
- maintaining the bookmarks is much easier (add bookmarks wherever you like; group bookmarks on subpages);
- add extra information (website logos, small pictures, etc.);
- no limitation to the number of bookmarks per webpage (instead of only 8 in landscape mode, or 11 in portrait mode);

An even better idea:
Free online space (say max. 5 MB) for every Kindle owner as an extra service from Amazon, to generate and maintain the bookmarks webpages on the
Manage Your Kindle page.
