Ruler guide color should be an inline feature in the tool panel
Changing ruler guide colors requires too many steps (Layout > Ruler Guides > Change color > Ok). When a guide is selected, guide color should be (also) configurable in the tool panel. This would make it feel a lot more 'instant'.

I was about to request a feature very similar to this. I had no idea the ruler guide colors could be set (per guide even) based on selection.
However, I'd also like to add that it would be nice to set the line type to dotted as well when the guide isn't *that* important. I realize I could put them in a separate layer and just hide the layer when not needed, but that needlessly clutters the layers panel with kludges.
