What's the savest way to remove the Dashboard from the admin area?
In wp-admin I've disabled index.php and renamed wpmu-admin.php to index.php. The admin area now opens on Site Admin, skipping the Dashboard, which is closer to what I want.
But Dashboard is still on the menu. Unfortunately menu.php is a code page. I can't figure out what's going on in that page.
Which lines can I remove or edit to remove Dashboard from the menu bar without messing up the system?
How can I rename the link on Site Admin to index.php? (It apparently works without renaming, but it feels wrong...)
How can I let Site Admin open default on one of the options, like Blogs?
