I like the context menu in the tag panel where you can tick/untick the desired fields. I wonder if ticking could be implemented for loading the tag panels as well?
And why not take it one step further by automating the saving of tag panels? It would be really neat if you could tick in the context menu to swap panel without losing your settings in the previous panel. (Currently, you have to save the previous panel before loading a new one.)
But even without automatic saving, just the ticking to swap panel would still be a nice feature of its own.
