I would like to suggest new filter APIs for copy and paste text hooking
like elm_cnp_selection_set_filter_add() / elm_cnp_selection_get_filter_add() (not fixed the APIs name)
This functions will support to modify the text before copying and pasting.
For example, If we want to add and remove application's tag before copying and pasting
we can use the above APIs.
please tell me your opinions.
