Thanks for opening this. Work ramped up, I forgot and then remembered... I get excited about this and then work happens. Good thing I like what I do!

No worries, we are all in a very similar boat by the look of it!

Hey @KelSolaar , Can i work on this issue? Could you let me know what are the weights that have to be exposed as i couldn't find the kL,kC,kH(as mentioned in the gitter message) in the code base.
