scroll bar for previous computations
Sometimes to avoid typing I want to use the cursor to swipe numbers or partial computations from the previous computation box at the top and paste them into a new computation. But this is impossible if the desired previous computations have scrolled above the top of that box, since as soon as my mouse leaves the scrolling adjustment bar, that bar jumps back to the bottom of its range, displaying only the most recent computations. Please keep the previous computation display fixed long enough for me to swipe contents from it.
On a related issue, I would prefer if the results of previous computations were displayed at the full precision at which they were initially displayed. Currently they are truncated to lower precision, although my input computation string is displayed in full.
