Re: Feature Request

These look like entirely reasonable ideas to explore for the next
round of development.  But please be patient for a few more days
while version 4.0 goes out to the world  (and maybe for a few more
weeks after that if the world discovers bugs that remained hidden
during testing).

Just for your information, another related idea that has come up
is to add a feature to "set label" that specifies that the label be
enclosed in a box, or oval, or whatever else turns out to be practical
to implement.
	set label 1 "TEXT" at <x>,<y> {in rectangle {fillstyle <fs>}} 

I also have another related patch (#908456) that is basically
ready to go but was too late for inclusion in version 4.0.
It makes 'plot with filledcurves' honor the fill style settings.
Would that allow the result you would like to have from your
proposed 'set arc ...' ?

That is a nice visual effect.
