There are a couple of minor inconsistencies in the casing of ui/container.js -
Notably, AddEditText / AddStatictext have dissimilar casing. Easy enough to fix but probably should be done with a deprecation warning to avoid breaking existing scripts.
* AddStatictext -> AddStaticText * AddTreeview -> AddTreeView * AddListbox -> AddListBox* *
A little bit annoying to decipher since the tools guide has some inconsistencies in itself, for example
ProgressBar / Scrollbar
