[Feature Request] Add an easy option to compare with another file (like Hashtab)

[PegHorse]

Actually, with current version 2.5, we can only search about Hash to compare with another one.
Please make like Hashtab, an easy feature to compare Hash with another one file directly without having to do CTRL+F, search etc...
Example :

I click the button "Compare a file"
Then i select the file, which give you this

Then very quickly we have our answer.

Thanks for the suggestion.

This is feasible, but I would prefer to implement it in a HashCheck-specific way rather than cloning the full HashTab UI. The first version should probably be limited to the single-file Properties tab: after the initial hashes are computed, a Compare... button would let the user choose another file, HashCheck would compute the same selected checksum algorithms for that file, and then report MATCH or MISMATCH.

For directories or multiple selected files, the behavior is less obvious, so I would keep the existing search workflow there for now and consider a broader “find matching file/hash among results” feature separately.

I am keeping this open as an enhancement request.
