Currently, there is no visual indication of what point the sheet is frozen at (which columns are frozen) which means users have to start horizontal scrolling to determine this.
Would it be possible to add a subtle visual cue such as a slightly thicker border on the last frozen column like Excel does? (screenshot example below).
I inspected HoT’s frozen columns in dev tools but couldn’t determine how their position is being controlled. I was hoping to find a unique CSS class that fixed them with position:absolute or whatever to allow us to apply some additional custom styling but couldn’t find anything.
