Please, focus on Editable Poly, it's what most Max users use to create something in Max.
Editable Poly needs some serious update.
+ Loop & Ring
- Ring selection with shift is broken since 2 years ago, fix it (make a box with 2 segments, convert to editable Poly and see how ring and loop selection with shift fails half of the time... very frustrating)
- Loop selection needs to add an option for: continuous loop selection
+ Circular
- Circle loop should work on continuous edges selection (actually only works on loops)
- GeoPoly should work on several faces selected (acting them as one), now it only work on individual faces
+ Extrude
- FIX EXTRUDE: Polygons gets shifted when they're non co-planar, this is HIGH PRIORITY!
- make extrude and inset work with shift, move: shift+drag=extrude, scale: shift+drag=inset
- add segments to extrude/bevel/inset
- make extrude smarter: remove internal faces, act like bridge when needed...
+ Cap
- Cap should create quads, instead of a huge ngon
+ Detach
- Editable Mesh has the option to Explode polygons into elements or objects, Editable Poly should be able to explode all its elements into separate objects
+ Selection
- Fix Preview Selection Multi, if it gets fixed it'll be the best way to work
- Double click on Polygon to select the entire Element
- Edit Poly should work on the input selection, instead of overwrite the selection
+ Symmetry
- Transform and Tools should have a symmetry option, so they work symmetrical without a symmetry modifier
+ Sculpting Tools
- Improve current sculpting, like adding mudbox sculpting engine to Max
+ Retopology
- Editable Poly should have an option to constantly project onto other meshes (this could live in Constrains)
- Automatic retopology (with and without guides)
- More and Better control over topology tools (Ribbon -> Freeform)
+ Normals
- Editable Poly should be able to directly edit normals
- Face Weighted normals should be the default
+ UV
- Editable Poly should be able to edit UVs, without adding an extra modifier (Unwrap)
+ Fix Maya Navigation Mode
- once Maya gets axed you have to make ppl comfortable in Max
+ Snaps
- Swift Loop should work with snaps
+ Tools Visibility and Shortcuts
- Some very useful tools are hidden from the user: insert loop, PolyShift Move, Edit Soft Selection... give them default shortcut and its place on the default Right Click Quad
- Unify Modeling tools under the same roof, they are scattered all over the place
- Grow/Shrink with shift+mouseWheel
