Newbie here.
I would like to add an autopopulation script when activated to present
options with checkboxes or the like, for comments and to create a final
comment from the options selected for pasting.

Example.
When i click the button "Custom Comments", a list of selections popup and
populates in a checkbox or soemthing, floating like a toolbar maybe.

Selections are and not limited to: Black, white, blue, red, shoes, tops....
When I checkmark "White" & "Red" & "Tops", then I click "Populate Comments",
it will show the comments seperated by commas like this: "White, Red, Tops".

Need to copy to the clipboard automatically and ready to be copied
elsewhere. The popup comments dialog needs a cancel button also.

Any simple ideas?
