Shortly (20131112) in enigma2 master the possibility has been added to change f.i. a service name:
- added possibility to rename services/markers and bouquets via channelselection context menu
When changing a service name unfortunately the name is only changed in the appr. bouquet. So if you have multiple bouquets (and who does not have that) and a service is available in more then 1 bouquets not all the services with the same name (SID, etc) are changed.
