I don't understand why there are two commands for comments with Calc
- insert
- show
With insert comment, I can only add text
with show command, this make the comment persistent, and I can also change the size and position's comment.

I think, the insert command should allow me to change the size and position's comment.
This has to be done frequently when adding comments, and it's boring to make what should be a simple task :
- Add comment (and fill text)
- show comment
- change size and position
- hide comment

Maybe, but not important, the show command, should only be used to make the comment persistent.
