For team collaboration, it would be great if all the settings could be exported to a file and automatically imported when the file changes (or when Dev Studio restarts).
Today, any changes to 'Inspection Severity' or other settings have to be done on every machine - this is unmanageable for a large group that wants consistent settings.
Also, only the code style settings can be externalized today. My team has checked a file into source control but it is still a manual step that every engineer has to do to load that file whenever it changes (even though they already have the new file because they got it when they got the latest code)
It is desirable for all settings (code style, inspection serverity, etc) to be externalized to a file that is automatically loaded when it changes or when dev studio restarts.
