Ding Ding Ding! 
Thank you very much.
I thought this a million times, but figured it must have been specific to my system, otherwise everyone would be requesting this.
I also recently saw and liked the idea of auto dividing panes by equidistant bars. Will return with link… Set panes to equal height/width
Perhaps with snapping at something like 10%, and the ability to shift the top, bottom, left or right bars up or down with hotkeys, we would never have to drop our thoughts and play the game of find that bar ever again.
I may be a little dramatic with exaggeration, but honestly when on laptop display, to this day, I never got it without being somewhat distracted by the process. In 4K it is a bit easier, I will admit.
Again. Thanks for requesting this.
