We need a way to make the scene panel in the project manager always visible in its own panel like the Properties Panel, Layer Panel, Objects Panel, etc. It should work just like those panels where you can change the panels place on the UI. There also needs to be a way to create sub scenes(purely visual) and scenes/sub scenes should be collapsible(essentially what RPG Maker does with its maps).
This would greatly increase workflow and increase readability of scenes while also feeling more familiar to people coming from most other game engines. In RPG Maker the maps are essentially the scenes(always visible). Unity and Unreal Engine have a Project tab which is similar. Needing to go one menu deep for such a common function really slows things down and larger project results in a whole lot of scrolling when you can’t collapse scenes.
