Hi :) as I see, you've uploaded new images but haven't replaced old images on the page and haven't removed old images, will you do this? otherwise this PR looks like not finished, because only new images have been added to the folder and haven't been used anywhere

Please, check that old unused pictures have been not only replaced but removed from repo;
please, check that list of actions is shown correctly, currently all lists of actions look like 1 sentence;
please, check Table of content on the right side of the user guide on the "Administrator in the User Interface" page, we have lost all links/sections comparing with the develop branch;
please, check comments for changes also.
