Smart Tab Groups

Mi*****

Finally! An extension utilizing the Tab Groups API! It kinda works but isn't great. There's no options or customization, so it's entirely up to the extension to decide whether to move a tab into a group or not. I assume by "smart" it simply categorizes by domain (e.g. "youtube.com"). Also, it only works on the foreground tab. Background tabs are not auto-grouped, which is very much the use case I'm looking for - open a bunch of tabs in the background and have them automatically organized into groups.
