Node graphs can become unmanageable when they have many connections, especially when several lines cross or are close together. A simple solution is to add colour to the lines. This can be done in two ways:

1. Highlight the whole line white on mouse over. Perhaps the connection handles, too.

2. Have lines adopt the colour of the handles they connect to. For example, a line coming from a vector source would be blue. It could fade to black or to the colour of the input it connects to - but fading from blue to yellow might be hard on the eyes.

Props to Enigmath for earlier discussion on this.

The current bug tracker is pretty hard to use, and may deter people from submitting bug reports. One possibility is to migrate to Launchpad. Some advantages over the current tracker are:
* More detailed search results, including number of pages of matches.
* Ability to add attachments when editing a bug.
EDIT: The current tracker does allow adding attachments, but there are other reasons to switch; see below.

As a bonus, it'd be easier to integrate blenderstorm with the tracker (see http://www.blenderstorm.org/qapoll/ideas/idea/8/ )
