This task lists operators not currently accessible using gizmos.

Which is an issue if we want to support selection as the dominant action, see: #66304 (Tools, Selection & Gizmo design).

This task lists tools that current aren't accessible from gizmos.

Irrespective of the default action (select or tool access), it would be good to support use gizmos for tools which currenty don't always have an obvious means of access.

Note: Tools with existing gizmo access have been excluded.

Tool	Gizmo	Cursor	Notes
Cursor		Arrrow	Transform gizmos for 3D Cursor tool should be visible by default, and a Drag option could be added too
Annotate	N/A	Arrrow	Doesn't act on selection, no gizmo
Measure	N/A	Arrrow	Doesn't act on selection, no gizmo
Extrude Region		Arrrow	A new 'free' area needs to be added, so you can extrude perpendicular to the view
Extrude Along Normals		Arrrow	gizmo uses average normal
Extrude Individual		Arrrow	gizmo uses average normal
Extrude to Cursor	No gizmo should be added	Crosshair	clicking should always extrude to the cursor position
Inset		Arrrow	gizmo should use average normal
Bevel		Arrrow	gizmo should use average normal
Loop Cut	N/A	Crosshair	Doesn't act on selection, already has own 'gizmo'
Offset Edge Loop		Arrrow	1D gizmo appears on the selection, so you can drag in the correct direction
Knife	N/A	Knife
Bisect	N/A	Crosshair
Poly Build	N/A	Crosshair	Doesn't act on selection, already has own 'gizmo'
Smooth		Arrrow	1D gizmo
Randomize		Arrrow	1D gizmo
Edge Slide		Arrrow	1D gizmo appears on the selection, so you can drag in the correct direction
Vertex Slide		Arrrow	New 'free' gizmo - drag on this to slide in the given direction
Shrink/Fatten		Arrrow	gizmo should use average normal
Push/Pull		Arrrow	1D gizmo
To Sphere		Arrrow	1D gizmo
Rip Region		Arrrow	New 'free' gizmo - drag on this to rip in the given direction

bisect tool also needs a more accurate gizmo with axis snap option

@WilliamReynish There is an issue with the 1D gizmo, I'm not sure how it's expected to work regarding do/redo.

Either:

Every time you drag the 1D gizmo a new action is performed (which is how nearly all other gizmo's work currently).
Adjusting will change the current operation (in that case how to perform the action again?)

@ideasman42 I think it could just affect 'redo' probably. With the same selection, there's little practical difference for things like Smooth. Keep tweaking the slider and the smoothness goes up or down. If you select something else, you can then start a new smoothing operation.

Making it redo is a bit odd since we already have a redo panel,

we can try making this both do/redo but think it could back-fire. eg.
it might be reasonable in some cases to inset twice.

@ideasman42 Yes - it's also partly why I thought at first that it would be much simpler to do the 1d gizmos just like this:

Then we don't have to worry about tracking the current slider between min/max, and we also don't need to worry about values being clamped from a fixed minimum/maximum.

@ideasman42 replaced all the slider type gizmos with a simple handle instead, which would always 'do' - ie perform a new action every time it is dragged. This should avoid all the issues mentioned.

adjusting (dragging the handle or just dragging anywhere in the viewport) will change the current operation, holding shift or ctrl and dragging the handle again will perform a new operation.

@dfelinto, while there are more todo's, I think it's OK to close this since remaining issues are minor and not so much design tasks.

@giuseppebufalo we ended up not using these 1d gizmos.
