#if 0 // good UI/UX blender ideas
ui density is perfect: font face, font size and icon sizes are perfect even in a low res 1366x768 scenario
viewport: not cluttered at all. vertical floating toolbar on the left, floating icons on the right
left icons are tools related to current edition mode, right icons are camera only.
left icons can be long pressed for a hovered submenu, right icons can be clicked or dragged.
non-matching text filtering works by disabling widgets, not by hiding them
window contents can be promoted to any display any other window content by clicking their [icon V]
there are no windows or minimize/maximize buttons
windows are grouped with a vertical toolbar inside the right bar docked section
you can only display 1 window at time.
panels can be dragged within a window and make much more sense than our approach
scene tree: can make collections/groups
widget tree drawing is much simpler than us, just a vertical parent line per collection and indented arrows per child
context menus are always like: optional icon (white), text (white), either optional input binding (gray) or submenu arrow
input boxes are super reactive
< > are hidden unless hovered
< > can be clicked to de/increment (release)
< > can be horizontally dragged to de/increment larger quantities (hold)
< > can be vertically dragged to include other Y,Z properties in the selection (hold)
0.53m can be clicked (release) or dragged (<-> hovered icon) (hold).
0.53m whole text is automatically selected when clicked.
you can enter units when entering values 350m, 350km, 12mi
you can enter math values: 30+20+sin(1)
numeric: units always specified: 0 m, 90o, 1.25x
numeric: epsilons (non-zero) displayed as -0.00000 even if digits cannot fit widget rect
operation context is split into different sections in menu bar: modeling, sculpting, uv editing, shading, anim, etc
cam 3d orientation gizmo top right: can be dragged (orbit cam) or clicked (reposition)
rotation gizmo: anchor can be positioned within world
gizmo: will display always initial position while dragging, and tape distance so far
right floating icons can be dragged: cam orientation, cam panning, cam zooming, cam iso/dimetric
ctrl-z undo, ctrl-shift-z redo
