A Google Chrome version of http://freestyler.ws/style/30034/gmail-select-links-restored ...never mind, http://freestyler.ws/style/30034/gmail-select-links-restored has been updated and--among other things--works with Chrome now. (So you can pretty much ignore this one. :D)

For a better Google Chrome solution than installing as a user script, just do the following to install the style as a Chrome extension:
(1) create a new folder/directory on your machine

(2) in the folder, create a file named 'manifest.json' and put this in it:
{
"content_scripts": [ {
"css": [ "main.css" ],
"all_frames": true,
"matches": [ "http://mail.google.com/*", "https://mail.google.com/*" ]
} ],
"permissions": [ "http://*/*", "https://*/*" ],
"description": "Restore the Select links above and below the message list",
"name": "Gmail: Select links restored (ext)",
"version": "1.0"
}

(3) in the folder, create a second file named 'main.css' and put the source code from the style in it, minus the '@namespace' and '@-moz-document' statements (and anything else that starts with '-moz' if you like, though it's not necessary)--don't forget the ending bracket for -moz-doc

(4) in Chrome on the Extensions page--in Developer mode--click on 'Load unpacked extension' and select the new folder you just created

(5) and you're done... edit the source as needed (then do a reload of the extension and restart Gmail to make your changes effective)
