How do you guys feel about recommending the jquery-ui-rails gem? So far, it seems to be working well for people.

I am having jquery-rails include jquery-ui into my project without this other jquery-ui-rails gem and was confused as to what was causing it to succeed after re-reading this updated documentation considering I don't have the jquery-ui-rails gem bundled into my project. I feel like the documentation should be modified to say something more along the lines of this:

If you wish to use jQuery UI as well, you can add this line to application.js:

//= require jquery-ui

Alternatively, you may wish to consider (and we recommend) the newer jquery-ui-rails gem, which accepts the same syntax.

After reading the transcript of discussion in the pull request, it appears that you guys are moving to remove the offering of jquery-ui in this gem, but until that is complete, I just think the way the wording is currently doesn't clearly convey that this gem offers the ability to use jquery-ui in your project unless you have the other gem.

Sounds good to me. The current wording is unclear indeed.

Do you want to send a pull request?

By the way, you should strike "which accepts the same syntax" -- it actually doesn't.

Ahh... Well the way it is written now led me to believe it was.
