How do I remove some lines with trades from my report in the MoonBot terminal?

From the MoonBot main screen, press the “Reports” button and a separate table will open showing all your trades line by line.
You can selectively delete some or all rows of trades from this report by clicking on the “Delete” button.
If you then want to see a report with deleted trades, you can do so via the menu “All incl. deleted” (show all active and closed orders, including deleted orders).
