I don't think Editshare have gone beyond stating they were going to take Lightworks to open source. The current position as stated on the Lightworks website is:

"Once the Linux and Mac versions are released the source code of Lightworks will become available. We cannot give a date when this will happen, but announcements and updates will be regularly posted on the Lightworks Forum."

This has been the road map for a number of years, unfortunately, the Internet rumour mill has been saying that it's open source, when it's not, it's currently a commercial NLE. Looking at how things worked out, it seems that the demands from actual users in the early days drove it into becoming a cross platform NLE. rather than straight into open source. Although, a number of people from the open source community have been and some continue to be active on the Lightworks forum,

How the open source Lightworks organization works remains to be seen, there are a number of ways it can be structured. To date, Editshare have generally done what they said they would do, there has been some conflict over the Free version because new users were having problems with the transcoding imports etc, through third party software like Eyeframe, so they allowed Lightworks Free to import the commercial codecs. However, the downside was a limitation to the exports, because Editshare has to pay for the licenses.

I wouldn't expect Lightworks to go open source before 2015, perhaps even 2016. Editshare could be said to be guilty of being overly optimistic in their time frames, they're not unique in that, a number of well known products have fallen foul of that.

The Lightworks developers are open to suggestions and even some that received a negative reaction from some users in the Forum have been put into the program. The Lightworks UI has been described as pretty loosey goosey by one user, so you've got options as to how you arrange things, however, it does have tracks on its timeline.

For anyone interested in seeing the Lightworks console being used, a user video with a shot showing various operations combined with the timeline can be downloaded over the next few days:

The first review I've come across of the current beta Lightworks on Mac:

Impressions of Lightworks on the Mac (http://www.moviemachine.tv/post/impressions-of-lightworks-on-the-mac/)

Some new users get confused by all the boxes that can build up on the screen and regard this as a problem. This due to Lightworks allowing you the flexibility to work the way you want, so you can have multiple bins and viewers open on screen, enabling you to work outside of the timeline or on different versions of your edit. This freedom allows you to organize very precisely or like a fridge door, depending on the requirements at a particular moment..

I've been paying attention to Lightworks since I first heard of it on previous discussions where people are feeling let down by Adobe Premiere. Here is a review a run into:
