Almost every build I run into a missing block to transition from 1/4 long edge to 1/2 block 45. There is a version of the proper block to transition from 1/4 long edge to 1/4 circle (a 1/2 block 45 except it is round). Please add the straight transitions along with the round ones.
I made a little "slicing" rig to illustrate some new shape possibilities. Mirror both of them, and you could probably cover just about any situation with 4 new 5-sided shapes.
