I have seen for long time that when I am downloading a 
website, there are some links which show error message and 
their id is shown in the error log. After sometime if I 
try to redownload those links then they are getting 
downloaded without any problem.


So I have a suggestion : if a button like "SKIP" can be 
added at the end of the process for the links showing 
error, there may be possibility to get those links 
downloaded properly and that can make the whole process 
more error free.
