BugHerd is an online instrument for bug reporting and bug management.
Test engineers can work with the instrument from the web page they are at that time, there is no need to leave the page.
The error reports and other elements of BugHerd are visible only by the project members, other users of the web application do not see them.
Small indicators are put on the page where the errors are, so the testers do not have to search the whole page in order to find the errors.
Testers can report, look through the errors, add tags to the errors descriptions, sort the reported errors by priorities.
