Retain last used state. (including opacity shading toolbar )

[darkRaspberry]

Is your feature request related to a problem? Please describe.
I always use your colour picker. Also I use opacity and shading toolbar but when i toggle it doesn't retain it on restart.

Describe the solution you'd like
When i toggle it to show opacity, It should retain it to that state after restart, so i don't have to toggle everytime i use it.

Describe alternatives you've considered
nope

Additional context
Its very clear and small request just to retain all the toolbar and sliders to last state.

AND very very thanks for your app. I use Linux and there are less apps for Linux and you just made a gold app. Thanks alot.
