I’ve recently started using the Defold editor and for the most part it’s pretty nice. What I do think is missing are “mouse grips” on the various window dividers. One has to hunt around until they find just the right spot to click and drag a window divider to adjust the pane. I find it a bit frustrating on the single line dividers between the Outline and Properties windows and the Assets and Changed Files windows. A small area on the divider, a small circle, oval, square or similar to provide a “grip” for the mouse pointer would greatly facilitate adjusting the window to which it belongs.
Cheers.
