It seems like the project browser is on the right side now and there’s a new layout of different features. Is this expected? And can I change it back to the old layout?
Hi! The new layout is expected with 4.2.5, and when you open a project for the first time in the new version, this tour should pop up:
If it doesn’t, you can click the lightbulb icon in the top right corner to start the tour:
If you’d like to switch back to the original layout, you can use the toggle button in the development settings
