The 'log' action seems interesting, but it feels painful to log lots of actions in this way when a step-through debugger could be used.
I've definitely looked through the updates since the last time I touched C2 and the line-of-sight behavior definitely seems the most interesting at this point.
Bookmarking seems like a great way to mark aspects of the project as 'to-dos' for later or for marking certain sections as potential causes for a bug that's going on.
I am mainly seeking an official developer response on any sort of debugger progress.
