It would be great to be able to save and name pane layouts for quick restoration or autoloading at startup.
If you bookmark (or otherwise save, e.g. in WF itself) the URL of a multi-pane layout, it includes the identity of all the panes. It does not include their widths (which is an existing request) but is otherwise quite useful.
I don’t know if other browsers do this, but Vivaldi has something they call Quick Command. When a bookmark is saved it is given a nickname, After that you type Ctrl+E and the nickname and it jumps to that Workflowy view.
