While LrC workspace set up is more simple than Photoshop's, Photoshop has a an option to do set it to a chosen default: (Windows>workspace)
This would come in handy with LrC when, as an example, you try entering keywords, not noticing you didn't quite connect with the keyword entry "box". When this happens a good number of keys that you hit are short cut keys and the screen flickers between various views. Sometimes it is easy to recover back to the normal workspace, but there are times it takes a while to sort it out.
(Maybe just a magic way to undo all those unintended keystrokes😊)
