Feature Request: separate edit post and comment

[braboobssiere]

currently the edit function edit both topic and comment and there's no way to only edit comment unless user specifically save all the post and tick 'ignored save', so it would be nice to separated them into edit post and edit comment (maybe a radio button for "edit post", "edit comment", "edit post and comment" with default on edit both)

I would like this feature too
