First of all, what is "monitor scene?" Regarding a titler rewrite, I have a couple of suggestions. The window needs to be more scalable than it is now - it is bigger than my screen on my laptop. Also, might it be possible to make it as an overlay on the clip monitor? Then, a tab sheet can contain the tools and other widgets? Then, eventually, a variant of this tool can be extended as a way to also use shapes/eye-dropper/wand for defining filter masks and drawing into the alpha channel. BTW, in thinking about masks (better term than "region"), I am thinking about a way to modify MLT to allow one to place special filters "Set mask" and "Apply mask" onto the filter stack. That way one could designate one set of filters to apply with a mask, another set with another mask, and others with no mask. The mask defined in "Set mask" would be used with all filters below it and above "Apply mask." And "Apply mask" clears the mask for filters below it until another "Set mask." When the "Set mask" filter is selected, it could expose the "mask monitor overlay widget" mentioned above.
