variable path for editors, plugins and so on

I upgraded this module and did it, as I lways do for other modules: delete the module directory and unpack the new module version in this place. After that, my editor was gone. Why? Because it was installed in the module's directory, too. And deleted with the module's directory, too.

Is it possible, to extend wysiwyg module that the location of the editors and plugins (by editor and plugin) can be specified? The default could be as current (sites/all/modules/wysiwyg/editor-name and sites/all/modules/wysiwyg/plugins/plugin-name). Thus I can move the editor to a location where it is prevented from deletion by drupal module updates.

This could also be a general issue that modules should not rely on pathes within the module's path for any additional files that do not ship with the module.
