Request: Options for disabling tabs and buttons individually

[DKConvista]

Hi there,

first, I want to say that this is a truely useful package. Appreciate your work on this.

I have a rather simple feature request regarding options to disable some functionality. It would be ideal, if one could pass parameters to the constructor for each button and tab to disable them:

• Brush
• Text
• Flip
• Rotate
• Dimensions (Height/Width)
• Clear
• Camera

(Also, a widget parameter for the "Save"-Button would be nice, so it could be replaced by Text("Apply") or Icon(...).)

Regards, Daniel
