Hi! Two questions.
1) Layout seems to work great on top, but other parameters aren't showing up correctly.
Perhaps this is intentional, as I'm not sure how often the non-'top' parts of layout are used. In Sage notebook this is supported well. It sort of works in CoCalc. In Jupyter not at all (yet), see
https://trac.sagemath.org/ticket/22663 for current discussion.
2) In Sage cell, the following yields an error (because of the generator):
@interact
def _(a = (0..20)):
print(a)
But this is clearly documented as working in the interact documentation for sagenb (hence the reference implementation). It does correctly give a slider in CoCalc.
Thanks, just checking in!
