One thing i do very often is navigate the right-hand part of the screen (where you see the contents of the currently selected collection) with the arrow keys. The right arrow key “opens” the GO so you can see the contents. If you try and close many GO drowdowns at the same time, defold crashes.
Another weird thing is collision objects. They are slightly different if you create a new one or add one from a file (in terms of the properties that are available to edit in the menu at the bottom right of the screen). Whilst we’re on the topic, it would be useful to be able edit the position of a collision object and not just its shapes from the main collection view.
