Possible bug, or at the least undesirable behavior - if the messages pane is disabled when the user enables the script console, the message pane/console does not appear. I found this very confusing; when I enable a view option, it should appear.
Also, not exactly a bug, but something which might be worth fixing: This occurs if any pane holding a wxFlatNotebook is small enough that it has to hide some of the panels and enable those arrows, and the user has clicked the right arrow to move to the tabs that won't fit. If the pane is then expanded, wxFlatNotebook does not check to see whether the panels can all fit into the new size. It only updates the tabs (i.e. shows as many hidden ones as possible, to the left of those currently displayed) when an arrow is clicked.
I hope that was intelligible...
