A suggestion: the integration of various pop-up property panels into a single (possibly tabbed) context sensitive panel – which would display detailed info on whatever audio or midi event is selected – showing for instance the actual filename as well as the project name, file location, data size, length in time. Additionally, allowing to rename the file/event/track or change settings such as bit resolution by editing directly in the panel.
Also, option to click on track name to rename track without popup track properties panel.
