There are a few problems with your request.
First, there is a dedicated thread for MLV App. It's linked on their Github page, too - no need to open another one:
Ask questions on the Magic Lantern forum thread.
Second, the change you are talking about was made less than 24 hours ago. A build including that change will be, very likely, made as soon as the authors decide to do that - they don't seem to offer nightly builds, so they might prefer to do some kind of testing before releasing, or whatever (I didn't follow this closely). There's no need to rush the process, just because you want this feature... yesterday.
On the contrary - lack of patience, in particular, demanding/pushing attitudes, might have the opposite effect. "Remember that people do free work because it is fun, not to get stressed by strangers"
