The Lighting Controller

I just noticed that the undo/redo buttons disappeared in the Editor - at least in the current beta version. Was this intentional?

Multi levels undo/redo is a long job. So far, we had no time to do it. Moreover, we recently started working on new big projects (we can not tell what projects), which let us know that we could not do this feature in a short time. So we decided to remove the icons, until we have time to do this job.

OK, thanks - I just wanted to know that it was an intentional change. As always, I will look forward to seeing the 'new big projects'!
