Pfft, Hannah Montana... that show was so unbelievable. I mean, how in the world were people fooled into thinking she was two different people just because she put on a wig!
To be fair to LCARS it doesn't follow the application window pattern modern graphic OSs do, so it's not surprising that hammering a windowing system to make it look like LCARS is not efficient. It's supposed to display smart contextual widgets which are more akin to Grafana mixed with home screen/desktop widgets with maybe a dash of what Microsoft was trying to do with live tiles on Windows 8.
