Currently we've got a very specific set of rules for the HTML that should be in the textarea. While this can be hacked manually, it would be nice to be able to have a custom function within the configuration file that would allow customised cleaning of pastes from programs such as MS Word, etc.
Sometimes it is necessary to clean up all text pasted into the editor. This function is good but not enough. So would be great to introduce new configuration option ForcePasteFromWord which will work likewise ForcePasteAsPlainText.
@caezar, please open a new ticket for it. This one is totally unrelated to it, and has been closed and release already a long time ago.
