Some minor things to consider for rc3.
There is USB Install in the control panel and USB Installation in the menu. It would be consistent to use USB Install in both places.
Apps Audit in the control panel is called Appsaudit in the menu. It could be changed to Apps Audit, for consistency.
In the control panel there is TCE Update. In the menu there is Update Extensions. It may be easier for new users if these were both called Update Apps (new users may not know what tce or extensions mean). It would also be consistent with Apps Audit. Apps Audit and Update Apps could also be put next to each other, as they are related.
On the previous release candidate (I haven't checked on this one) when running TCE Update, and new directory is created called upgrade. This new directory could be called update.
