I see what you did there :D
Well structured post, well thought out idea. I learned a thing or two.
Even if this doesn't get implemented you've done your job.
I'd love to use something like this.
Yours seems pretty decent but relatively less discussed than most of the other ideas I like.
I Suggest that you edit the OP including the images you've uploaded as comment. Makes a better impression.
Let me tell you something, your presentation is top notch. Even if i don't use these features your job is accomplished. You've impressed me :smile:
Impressive stuff, not my cup of tea but props to your efforts
