No need to apologize! It's actually very good English AFAICT.

Well, Sketch has enough depencies as is and adding another one will make
it even harder to install. However, there could be room for an optional
OpenGL based renderer in 0.7.x, if somebody is willing to do the work.
Sketch 0.7 already has two renderers, the gdk-based one and the libart
based one.

Yeah, it's a little late. Switching to yet another toolkit will not help
Sketch development at all.
