Implement Eclipse like "Abbreviate package name" setting.

Eclipse has a settings for custom rules to define replacements for how package names are shown;

com.mycompany.myproject=..
com.mycompany=..

Something like the previous example make Eclipse replace these package names with dots. This make things less repetitive and helps reduce the need to have a wider primary sidebar in order to read the class names. Maybe showing the complete package name on hover is good too.
