I know that some are wondering, if I am still here. Yes I am :) 

I get many emails asking me, if I could update that or do that for them. 
Sorry, but I am concentrating on other projects right now, that support my family.  
Many use the horizontal accordion for commercial projects, but never really thought about giving something back. 
Some sent me $1 or even less in the past, which not really motivates me to extend or fix the available codebase ;) This hardly gets me a cup of coffee ;)
I have been working on it internally, but have no open updates planned for the near future.
