[Eeglablist] Extra channels next to the EEG-data

I'm enjoying EEGLAB also because it offers a nice set of visualization facilities. Nevertheless I miss one feature which seems to be rather relevant for many other researchers too. It is a feature of storing, scrolling, processing, etc., of some extra data channels.
What I actually do is statistical analyses of continuous EEGs. The results of my analyses are also continuous signals often having the sampling frequency which is different from the EEGs. What I would like to have is a possibility to manipulate simultaneously with the EEGs and the results. At least I want to look at both of them at the same time (scrolling). Currently I have to append the results to the EEG.data array, but it has several drawbacks such as that EEG.chalocs structure has to be also maintained properly. I can also plot the results in another window but it is also a bad solution since then I cannot scroll it with the EEG.
So, is there another opportunity in EEGLAB which deals with the EEG and results (e.g. extra channels) simultaneously? If not, then maybe we could think about how to make it efficiently, for example a kind of EEG.result structure?
