The package window

[Namnodorel]

The package sidebar is not resizable, which can lead to problems when working with long or nested package names: http://puu.sh/ybELb/cf0520bbb8.png

Also it would be useful if you could expand/collapse packages like in InteliJ (http://puu.sh/ybEUi/4dca1ed7e7.png) instead of always displaying the full package name of each and every (sub)package.
