Feature Request: Skewb NS 2.0 / Advanced trainer (layer solved) and 2x2 4 move scramble generator

[xSkewber155]

Currently learning NS 2.0, and it would be good if there was a scramble subset that gave 'layer solved scrambles' for skewb, even better if you could select sub categories (such as pi + swirl perm or peanut + o perm) as I found the ability to select the OLL really helpful when drilling CLL algs on 2x2. It would be great to have a layer solved subset for skewb, as many would use it to practice advanced or NS 2.0, or small sub categories of them. The 2x2 4 move scramble generator would be very useful, as it would help many recognise, plan, and execute 4 move solutions, Thanks for reading :-)
