One color for gradient on Sidebar
ID сборки: d50a87b2e514536ed401c18000dad4660b6a169e
OS: Windows 7 Home Basic x86
Sidebar Properties section, subsection Area to configure the gradient is only one color instead of two (see screenshot)
Hmmm, yes as displayed in the Sidebar's Area content panel, a selection of gradient fills shows only one swatch of the gradient.
The "more options" button top-right, launches the Area dialog, where on the Gradient tab (shown in attachement 113542), two color bars of the gradient are provided the start "From" and end "To"--as well as a larger view of the color sample.
Point is the Sidebar content panel shows the the sample swatch--not the start and end colors of a gradient. But since the same widget shows a sample swatch for each Area fill--Color, Gradient, Hatching, Bitmap, from UX perspective showing only the swatch is probably correct.
But some folks might like more convenient way to change the start/end values of the gradient than the Area dialog panel.
Perhaps making the swatch itself (at least in Gradient fill mode) a button that launches the Area dialog open to the Gradients tab?
in 5.1 this enhancement will be implemented
