Overall feedback about panel design

I actually miss the overview we had in the old airlab. This was helpful to see which clone is conjugated to which metal.
There I was always sure not to have accidentially two antibodies with the same metal in my panel. In the current version it is not a problem to have two antibodies of the same metal in the panel without noticing.
I like that the panel appears at the right side, but it would be great if it would be ordered by metal or possible to order it.

Alternative panel editor view is implemented similar to old AirLab behavior.
