Hide bounding box when adjusting design effects values

[myfunnyandy]

Is your feature request related to a problem? Please describe.

This request is a variation of this other one, that solved the same need but only for size and position values.

Describe the solution you'd like.

The bounding box should be hidden when adjusting values in the design sidebar (at the workspace right sidebar) so the result can be better seen.

The values to be considered should be the ones for:

• Layer opacity
• Fill
• Stroke
• Shadow
• Blur

Note

It would be perfectly fine to break down this issue into different ones to treat separately the different properties.
