It would be nice if the programmers would spend some time in adding code for this command; or adding an internal timer that would autosave the current layout if it is an already saved layout that one is working[study-ing] in.
Sometimes I forget to MANUALLY go and save/update the layout snapshot, or close the program without thinking - bummer lost that one!!
oopps just found it somewheres else:

Logos 5.0b added the concept of an “active layout”. The active layout’s name is displayed in the title bar. You can click “Update active” in the Layouts menu (or press Ctrl+Alt+L/Cmd+Alt+L) to update the active layout without having to remember its name.
