**Jot Down Some More Ideas Here**

([AMG]: I'm starting this section for people who want to make a note of an idea but don't want to create a separate idea page until it starts to take shape.)

***Alpha Blending in the [Canvas] Widget***

[AMG]: I'd like to be able to specify transparency for items in the [canvas].  One possibility is to let color names be augmented with an alpha value 0.0-1.0 (or 0-255, whatever).  Another is to add a separate -alpha option.  Each approach has pros and cons.  Alpha-tagged color names permit separate levels of transparency for -outline and -fill (and -activefill and -disabledoutline and all the others) (or -background and -foreground in the case of [[deprecated]] bitmap items), but they don't mesh well with image and window items which take neither -outline nor -fill options.  An -alpha option would cover all canvas items, but doesn't permit separate alpha for outline and fill.  Obviously this idea needs a bit more thought, though I write it here so it doesn't get lost.
