Experimental or work-in-progress testing TKKS features can be found on TKKS.co!
If you want to test out any new work-in-progress TKKS features, functions, or new concepts, you probably want to search the TKKS.co website!
The TKKS.co website is an alternative & experimental TKKS website created & designed for experimental testing features. (Well, actually it was originally intended for redirects, but experimental features seem more useful.)
On TKKS.co, you can test features for a large variety of TKKS projects including, but not limited to: Art displays for the TKKS Culture of Perfection website, early beta features for the TKKS Perfection Search web browser extension, & most notably, work-in-progress concept features for the TKKS Website Reconstructed.
