 In this case this extension will generate a .desktop in the `journalctl` when you click the save button (<img src=icons/save-symbolic.svg width="14" height="14">). Search `Generated a .desktop file` in `journalctl /usr/bin/gnome-shell -r` to find it: `journalctl /usr/bin/gnome-shell -b -o cat --no-pager | grep 'Generated a .desktop file'`. To make it work, You need to copy it to `~/.local/share/applications`, and relaunch the app and save the session again. This extension should be able to restore the workspace, state, size and position of this application.

-I tested on Anki, VirtualBox machine and two .AppImage apps, they all have no .desktop and are launched in the terminal. By using the generated .desktop, Anki, VirtualBox machine works. One .AppImage app works. Another .AppImage app is `Wire_x86_64.AppImage` and doesn't work, because the command line returned is something like `/tmp/.mount_Wire-3xxxxx/wire-desktop`, file in the `/tmp` will be deleted during the OS shutdown and start.

 It's impossible / hard to query the command line from a process, the pid of a window might not be right too and I don't find a standard way for this.
