Sorry, I read through comments more thoroughly an found that "Atlantic" already explained that in a comment (#163):
"There is no Rig Manager 3.0 yet. Only a beta release of RM to manage Profiles, but not any kind of editing nor previewing presets.
The improvement of OS 7.0 is the new way of scrolling presets that lets you scroll by categories of effects and types besides the presets themselves. In previous OS versions you had to browse each one of the presets before getting to the one you where looking for."
