Limit scope of what the tool does when only migrating lists
Currently the SPMT tool does a lot more than it should when migrating only lists or libraries. For example - it changes the site title, activates features (web & site scoped) that are completely unrelated to list data that's being migrated.
It's rather frustrating when having spent considerable time setting up a site where features need to be deactivated and other settings reverted. The incremental process does the same too. The tool also resets and removes views, as well as surprisingly deletion of indexes that were put in place to assist with filtering in views.
