You shouldn’t need to use a workaround just to put the level editor to the same rank as blueprints. I like having subdivisions between windows and tabs, so limiting the window count to 1 is especially bad. Someone on another thread apparently found that by commenting out ONE LINE OF CODE you could get rid of the window hierarchy causing this whole issue. It’s a completely warrantless limitation.
ten years and still no solution?
+1 this. The hardcoded Always On Top behaviour is really suboptimal
For anyone who would like to have the blueprint editor window (and other editor views besides the level editor) function the same as any other window (meaning you can alt+tab between it and the level editor window, and the currently-focused window will be on top - just like most other applications with multiple windows), see my post here for instructions on how to enable this functionality (working in UE 5.3.2, not sure about other/future versions).
This alleviates the confusion/frustration when trying to alt+tab to some other app, and needing to hit tab multiple times with alt held down. It also allows you to dock a different content browser (1-4) in other editor windows, as well as the message log, output log, etc.
Basically, with this change, you can easily use alt+tab to switch back-and-forth between whichever UE windows you want, and also between any open UE window and any other open application’s window(s).
