`C` cosmetic, `F` functional, `P` performance, `B` bug fix

C hide the bed with a checkbox? indication of part outside printable area?
C set page background color? or dark mode?
C better small screen support (on screen button for hiding side panels, compact selectors)
F widget general add-ons (fdm supports, cam tabs)
F extend mesh object to store raw + annotations (rot,scale,pos)
```
share raw data w/ dups, encode/decode
```
F remember object's original position/orientation for reset/multi-object import alignment
P bail on decimation if it's proving ineffective
P improve decimation speed by avoiding in/out of Point
P server-side processing (determine protocol and storage)
P refactor / simplify POLY.expand (put onus on collector)
P cloned objects should share same slice data unless rotated

P disable infill fingerprinting for gyroids
P refactor thin fill to use outline and inside poly normal dist to self
F polishing and other non-planar work
F manual support addition / control
F gradient infill https://www.youtube.com/watch?v=hq53gsYREHU&feature=emb_logo
F first layer segment large flat areas for better fill reliability
F adaptive column to compensate for fine or layers that finish too quickly and melt
F apply finish speed to exposed top and underside flat areas
F expand internal supporting flats
F first layer support speed should be same as shell speed
F add lay-flat auto-rotation or from selected face
F determine start point from gcode preamble
F trim support offset from layer below
F feather sharp tips by reducing extrusion in area of overlap
F dual extruder and swapping extruder support
F option to support interior bridges when 0% infill
B fix multiple part layout export offset (resend position @ print time)
B check for support / brim intersections on first layer
B fix wrong first point in general (all modes)

F lead-in milling
F have 'clockwise' setting use spindle direction, etc (climb/conventional)
F add option to spiral in vs out (optimal tool life) vs mixed (optimal path)
F ease-in and ease-out especially on tab cut-out start/stop
F add endmill spiral direction to influence next point
F warn when part > stock or cuts go outside bed
F add M03 tool feedrate support (https://forum.grid.space/index.php?p=/discussion/14/s-
F compensate for leave-stock in outside roughing (w/ tabs)
F check normals for downward facing facets. mark top for slice skirt/pancake
P refactor slicing around flats w/ interpolation instead of culling
P optimize away topo generation (for z hop/move) when part is flat
P store tab and camshell polys in widget.topo to minimize z on edge moves
P linear finishing going back to z top too often
P option to skip milling holes that would be drilled parameter#latest)
P crossing open space check point is outside camshell before returning max z
B fix ease down and re-enable (need failure case)
B fix zooming, workspace thickness for larger workspaces
B fails in pancaking (clone) when there are no sliced layers (like z bottom too high)
