Hi everyone!

We're about to release the following changes to the developer preview:

* General
- The "Enable Backbone Constraints" checkbox in the behavior tab has been renamed to "Enable Cut Bands". This checkbox now should modify only the behavior of the cut bands, and NOT the rest of the backbone. This should fix *some* of the issues with wiggle.
- A new tool has been added - Idealize. Idealize works on a segment of backbone and sets the inter-residue bonds to their 'ideal' angles.
This tool should be very helpful for closing cuts, and resolving backbone quality issues. This tool is available anywhere where local wiggle is available. Additionally, there is a script hook called "IdealizeSelected".
- A Delete button has been added to the track dialog. Pressing the button will delete your track (with a confirmation prompt) and return you to the default track.

* Electron Density
- There is a button in the Electron Density Panel to focus rotation on the density. You can use the HOME or Q keys to refocus on the protein.
- The density score of a residue may now be viewed in the tab menu
