Description of problem:

There are two buttons labeled Deploy in Bundles view

1.  xzy bundle -> Destinations -> Deploy
2.  xyz bundle -> Destinations -> some destination -> Deploy

I found it confusing.  They're not doing exactly the samething. In #1 you must always have to create a new unique destination as there is no dropbox to select existing ones.  

I suggest creating just 1 deployment wizard with a top progress indicator and clearly define concrete steps, eg 1. select/upload bundle, 2. select/create new destination, 3. select bundle version, 4. specify additional options, etc.  The wizard then can be launched (with appropriate info filled in) from top level Bundles view or in destination details view.
