- The maximize button does not work anymore (nothing happens).

The two UI errors listed below occurred when I first opened an existing project that was made with v0.2.2 (WIN) after installing 0.3.0 (WIN). I was able to reproduce these errors with new projects as well. However, after I created a new project, saved it and then opened that same project via the "open" button the two bugs listed below no longer occur and I cannot reproduce them anymore. It started working again for both new and existing projects.
- The audio file list is empty but the sounds are present on the map and are working (see screenshot below). This happens with both new and existing projects.

- The button to hide the media list does not work anymore (nothing happens).
