LTI content usually has its own design and navigation. Currently such content can be embedded using an iframe or opened in a popup window.
While the embedded configuration has the best integration and usability, it can not use the full space due to the menu. Layout wise the content might clash with the OO layout since it is delivered by another system. The popup method on the other hand opens a new window which is not desired from a usability stand point. It is unclear for users how they have to deal with the two opened windows.
A new mode should be implemented: in iframe, but LMS hidden. The same mode is available also for tests and scorm elements. Only a back link at the top is rendered by the lms, the rest comes from the LTI element.
