Usability Tipps

Hi guys

I really like this Addon, but I have a problem with the usability.
Totally I have over 5000 channels and they are sorted in approx. 20 Groups.
I’m using the Wetek IPTV Box with a default remote Control.
When I’m watching a Channel per example Channel X from Group G1 and I want to switch to another Channel Channel Y in Group G2, I need many clicks and that frustrates me with the time:
LEFT (for Menu), DOWN DOWN DOWN DOWN DOWN (to Groups), OK (To get all Groups)
After that I can choose another Group and select Channel…

Is there a Short-Cut or can I configure a shortcut, so that I get this Group-Overview with pressiong only One-Key on the Remote Control?

Thanks and Regars
Mario
