Hi Milindstrom,
I wish you had a brilliant Christmas! 
Thanks for the feedback! While we’re going to start designing brand-new models soon, we’re currently focusing on upgrading our existing lineup first. I’ve posted an update since the work is nearly finished. Let me know if this looks good to you!
