Would be nice to have a “Select Parent” Shortcut.
Basically adding this function
and by default selecting the parent directly above the currently selected element.
Another implementation would consist of functionality like switching tabs in Chrome: Cmd/Ctrl+Page Up = go tab left, Cmd/Ctrl+Page Down = go tab right. In Bubble that could be Cmd/Ctrl+Page Up = [Select parent] and Cmd/Ctrl+Page Down = [Select the element under the current element] — as a result of these functional shortcuts you could very quickly navigate across multiple layers
