I also added some beta content for the I series by @daniel398767: the I-L series. Basically an LWB more luxurious version of the I series. See for yourself. (yes, we were first making this. theres an alternative version by another user coming up too)
Furthermore, I did some tweaking and fixing here and there. Nothing worth noting.
