First thanks for Dmitry Kashin's hard work,and I want PE to perfect urgently. :)
1 PE should have the ability to switch properties file loading between module and project. The module usually maintains its properties files,and modules are independent on their setting for using properties files. PE should have ability to loading properties files under module root directory independently. Code assistant and navigator will be more effective.
2 PE should have the ability to ignore some properties files. Now a lot of frameworks or tools use properties file for their setting,and these files are not used during our software development,such as Hibernate's hibernate.properties,Mavnen's project.properties and so on. Loading these properties file only wastes memory and give us complexity for using some PE's functions.
