With the new versions when searching the project, the element highlight is now very confusing because the colors and shadows they use are very similar to the rest of the elements.
In the example image I indicate with an arrow the element highlighted when clicking with the mouse and it turns a shade of gray one shade darker than the rest. I do not find an option to change the style or theme where the element that has the focus is clearly highlighted with a totally different color and clearly visible to the naked eye.
Using the Dark theme is even more confusing to distinguish the element or activity that contains the focus.
