There are a lot of outdated screenshots on the help page about the User Interface.
Go to Help -> User Interface
Any image that shows creator has still "Build Issues" ToggleButton at the bottom bar. (don't think that's too bad)
On this site is a description for the "Build Issues" pane - this is outdated as well - this pane is now "Issues" because there are not only build issues listed.
Go to Help -> Finding and Replacing
Advanced Search has now moved inside the output panes (like Issues, Search Results and so on) instead of being a dialog.
