[Feature]: Consistent UX for drawing, expose, and topology tools

[kwvanderlinde]

Describe the Problem

I don't use the drawing or FoW expose tools very much, but I do use the topology tools a lot. When I have to use the other tools, I find them confusing because they don't control the same way as the topology tools, despite being very similar. If I'm in a game, I simply can't work quickly enough if I ever have to switch back and forth between the tool types.

I've also noticed that the modifier keys are not quite consistent between shapes, and are especially not consistent between tool types. The drawing tools and FoW tools seem to be consistent with each other, though the different shapes have different meanings of the modifier keys:

Modifier	Rectangles & Ovals	Polygon & Freehand
None	Draw, no snap, origin is top-left	Draw, no snap
Shift	Erase	Erase
Ctrl	Snap to grid vertex	Snap to grid vertex
Alt	Origin is center	Snap to grid center

Meanwhile the topology tools are just all over the place:

Modifier	Rectangles & Cross	Ovals	Polyline / polygon
None	Draw, no snap, origin is top-left	Draw, no snap, origin is center	Draw, no snap
Shift	Erase	Erase	Erase
Ctrl	Snap to grid vertex	Snap to grid vertex	Snap to grid vertex
Alt	N/A	N/A	Snap to grid center

The Solution you'd like

I would like the following rules to apply for all tools:

Modifier	Behaviour
None	Draw, no snap, origin is top left
Shift	Erase
Ctrl	Snap to grid
Alt	Snap to grid center
Space	Origin is center

The only exception is for polyline and freehand tools: these don't have a useful "center" for this, so the Space modifier will simply do nothing for those tools.

I picked Space as the modifier for "origin is center" because I felt I needed a replacement for the old Alt behaviour that some of the tools have. I don't know that it's a good idea, and I would be happy with just about another key, too.

Alternatives that you've considered.

Another aspect of this is that drawing and expose tools show measurements to the user, but topology tools don't.
