Suggestion to solve overlapping hints

[ckat3]

Sometimes when links are too close together, hints (especially those with two letters) will overlap. A couple of ways to solve this could be: one, erase the first letter after it is pressed – so e.g. if I have hints for AA and AB etc, after pressing A the hints would only show A, B etc, thus hopefully reducing the chance of overlap; two, after the first letter is pressed the hints could have their drawing priority inverted – so that if horizontally aligned overlapping hints tend to cover each other's second letters, now they would tend to cover the first, already-pressed letters instead.
