There are still about 30-40 people from Russia puzzling on the site (!)

One of them sent me a request/suggestion: an "auto fill" for pencilled numbers in cells.
So you'd click a button, and all options for all cells would appear automatically everywhere,
and would also be automatically updated when you enter a new number somewhere.

A 2nd suggestion was to have a "pencilled numbers copy+paste", so you could quickly
enter the same guesses in a new cell.

What do people think?

(I suggested posting this to the forum himself, but it appears he does not want to)

I wouldn't mind this (most Sudoku websites do the same) but you have to keep in mind this will trivialise most of the puzzles on the site, especially the easier difficulties and the 12x12/15x15 puzzles. Calculating cage combinations is part of the difficulty in my opinion.

It is only when I am doing difficult KS that I would use a "copy and paste" feature.

I agree with Billa that calculating cage combinations is important to solving puzzles.
