Later next week, the first release Candidate should be available, which will feature prototyped selection methods (saving time and code), some improvements for the #id selector and more and better documentation (all in english as well as german), CSS3 Selectors (as plugin) as well as some more plugins.
Meanwhile I hope that some more javascript developers have a look at the source and share their opinions with me. The most important questions: which selectors would you choose for the core version? What pages would you like to use tinyJS in? Which abilities would you like to see as plugin / within the core?
