Hi Marco, for #1 curve antialiasing in MoI is pretty much already as good as it's possible to do so I don't really expect to be able to improve that in particular. Do you have an example where it isn't working well?

For #2 I'm afraid that display glitches in the viewport display are difficult to avoid without taking a hit in speed at the same time. I do have some ideas on possibly improving that particular type of artifact but it remains to be seen how much of a speed hit will be involved.

For #3, that is something that I do intend to focus on, however your other requests would generally come at the expense of speed so you're kind of asking for mutually opposing things on your list here... ;)
