There are websites that check if you are a robot or not!I suggest that this
software should have the feature that lets the users manually sign in and pass
that robot checking barrier. 
For that purpose, the developers of HTTrack  may link the software with
already existing web browsers like chrome or the developers may introduce
their own small browser inside the software that lets people open a website,
sign in and pass that robot checking barrier!

P.S I know that the feature of sigining in is already available but if it is
manually done using a browser, it would be better! 

Please let me know if you introduce this feature!

Thank you!
