I am still a bit sad that window shading isn't supported. I wonder if I am going to continue saying this until I am like all those people 20 years ago complaining about things they liked in CDE not being available in more modern DEs.
You can move the title bar around, and depending on the window manager either double clik to drop down again its contents, or by leaving the mouse pointer for a few seconds hover it, it will temporarly reveal its contents.
The setting is still there (or was there until really recently).
