1) I ended up with large files with many point series in the left-hand list. I'd appreciate if there was a feature to display all items in the list, or display none (check all boxes, check none).

2) With long lists like I mentioned above, it would be interesting to allow a hierarchy (like folders) in FunctionList. If a hierarchy is impractical, it would be a fine work-around if we could add separators (i.e. horizontal line) in the list, just to organize things a bit. I use "text labels" which I don't display (box unchecked) for this, but it's a bit lousy.

Thanks!
