[ ] Fillet in sketch mode
You want to fillet two edges? Yes, we will need some more advanced curve editing tools definitely.
[ ] Split objects with a surface
Yes, this one is on the roadmap.
[ ] Pattern tools
Yes, this is on the roadmap too.
[ ] Need to be able to extrude a line on a solid object
You mean a sketch on a face? Or an edge that connects two faces. The first one wouldn't be too hard, the second one is not straightforward.
[ ] Move tool with adjustable center point for off center rotation movement
On the roadmap, will be done in the next few weeks.
