Feature request Drawmesh, Crease subD

While looking at the car tutorial and playing more with Nvil3d there are something I wish for the future if it is possible...or if it makes sense...

Drawmesh
On the Porsche modeling tutorial where the front light bezel is created
In drawmesh you draw the circle shape then circularize...but how about the circle creation option is already there? with the option (attached) from center, 2 point or 3point ...I would guess making this fast program even faster. while duplicating and offsetting the shortcuts are e bit weird to remember...D for duplicate O for offset seems easier to remember..but I guess these can be changed.
when scaling the circle it would be nice and a bit more accurate that the circle remain on the mouse pointer and I guess it would make it faster as well.

When cutting for the wheel wells again drawing then adjusting then cut.
If one had circle option ..just create maybe adjust then cut.
are there measurements diameter when creating circles? this would be nice for people with 3d printers.

Crease sub D
I think it would be nice in the crease subD menu there would be an option that will hold lines.
what i mean if you have a square or a straight line selected it will hold its place or shape even after subD....something similar to the crease sub D. does to avoid the need to add more loop cuts.

Is there a way to make text in highlighted yellow bigger?

Tnx!
