Code Completion for Java/Groovy/Grails and Projects

First of all, texttastic is great. Bought it same day as my new iPad.

I'd really like real java and groovy/grails code completion. That, together with svn integration will be just perfect.

Also, it would be great to have the concept of projects, it could be as simples as group of files, or a folder, with a name and associated language, and source (svn, dropbox, iCloud, etc)
