Over the years working on Kentico, I've developed a bit of a personal library of custom Web Parts, Form Controls, and systems. A majority are already up on the Kentico Marketplace, however due to time constraints sometime have not made it up there (as i try to publish my tools in all Kentico versions 8+, and some were developed and never migrated to the other versions yet).
Below is a listing of the various tools. By clicking on them, you can get more information about them, how they work, what they are for, and how to obtain the tool. If any tool you see here isn't on the marketplace, or isn't on the marketplace for your Kentico version, just contact me and I'll get it converted for you.
When it comes down to it, much of Kentico is about relationships. Child pages, categorization, related pages, we leverage all of these things in order to link one object to others.
However, Kentico's default tools and interfaces have something left to be desired. This toolset fills in all those missing gaps and provides you with UI templates, form controls, helper macros and classes to relate Pages, Objects, and Categories together in any way you wish.
