It would be useful to have a feature that allows users to filter and view all hands played against a specific opponent within an uploaded hand history. For example, being able to search a player’s screen name and instantly see every hand you’ve played against them, whether heads-up or in multi-way pots. Naturally, their hole cards would only be shown if the hand went to showdown. If there was no showdown, their cards would remain hidden. This feature would be a valuable tool for reviewing past hands and studying opponent tendencies.
