As promised in the blog post earlier tonight announcing the first Alfred v2 beta, here are a few workflows Mega Supporters can import to get started.
Search Google with a keyword or a hotkey, and launch in various browsers. This is a great starting point for creating your own alternative searches.
Open Folders in TextMate
Use the "folders" keyword to perform a filtered search on folders only, then open then automatically with TextMate. Change what file types you search or choose a different "open with" application for a really useful quick filter to your files.
Paste as Plain Text
Use a hotkey to paste the current contents of your clipboard as plain text.
Should I watch this movie?
Type "movie" and the name of the movie you want to watch to search for trailers on YouTube (using Chrome - handy if you don't otherwise have Flash installed on your Mac), open IMDB for more details and open Rotten Tomatoes to find out how bad that movie really is.
jdfwarrior's Alfred v2 workflows
If you still want more, check out David's Tumblr for a few more useful workflows. He has created a Chrome Bookmarks search which presents results in Alfred, a Google Auto-complete workflow, a fantastic-looking Rdio search and a Mail.app search. He's been working hard!
Looking forward to seeing what users will create over the coming months! :)
