What are the footprints a magento module can leave in the magento system?

Question

I installed a module/extension but it does not work well for our needs.

I want to completely delete the module with all its footprints.

I removed the following:

1. code pool - deleted the folder related to that module under community folder,

2. deleted design files at design/frontend and design/adminhtml,

3. deleted email template files of that module at locale//template/email/,

4. deleted Namespace_ModuleName.xml at etc/modules folder,

5. removed configuration variable values of that module at core_config_data table,

6. deleted module entry at core_resource table,

7. deleted all tables created by that module by looking sql file of the module

what else I need to remove to uninstall the module completely

Am I doing correct or is there any other standard way to uninstall magento extentsion ?

Here's the personal list I made up over the years:

• app/code/<codePool> folder
• app/etc/modules file
• app/locale translation and email files
• app/design layout and template files
• js libraries
• lib libraries
• skin js, css and images files
• shell scripts
• extra non native folders

Regarding database:

• Tables created by the module
• core_config_data entries
• core_resource entry
• Possible extra columns added to native Magento tables
• Possible attributes added to native Magento entities (this is a very important one, especially if a backend model is used, removing the files without removing the attribute could potentially break the websote)

One useful module I use to properly uninstall my personal modules is https://github.com/magento-hackathon/MageTrashApp it lets you create uninstall scripts for both files and database for your modules then you can uninstall them from the backend.
