Where can I find those features?
Most of them are visible in the Admin/Settings area of Piwik under the section "Diagonse". The debug bar should be visible on the bottom of the page. In case it is closed there is an icon on the bottom left to open it.
How do I get to the terminal?
Open "Edit files", move your mouse to the left and a navigation will open where you can select the terminal.
Where is my ZIP file that I have generated in the file editor?
If the browser doesn't offer you to download the ZIP it'll be placed in plugins/PiwikDebugger/libs/icecoder/backups
When I edit a file in the file editor, where can I find an untouched copy of the file?
Before changing a file the first time we will generate a backup within the folder plugins/PiwikDebugger/libs/icecoder/backups
How can I restore all edited files?
Open the file editor and click on the menu entry "File => Restore all edited files"
