Enhancement: remove/ignore spaces in a hash string when checking

[Javaru]

Some software downloads publish their hashes in groupings with spaces such as FE96FB7F 40244BED DAFF2FD7 A49BF0F8 (one example). It would be very useful is those spaces were removed when the string is pasted/entered into the "Check Against" text field, or ignored when the check is run (as currently happens with leading and trailing spaces). Thanks.
