Whenever I use my shortcut to open the home folder it's always positioned at the bottom left of my screen as shown below.
How can I open it in such a way that it would pop up in the center like this?
To make sure the window always appears on the same poissition, create a shortcut to get it done:
xdotool, to position the window:
sudo apt install xdotool
Add the following command to a keyboard shortcut:
/bin/bash -c "nautilus ~ && sleep 0.5 && xdotool getactivewindow windowmove 300 300"
Where you need to replace
300 300 by the actual position (x/y) where you want the window to appear: choose: System Settings > "Keyboard" > "Shortcuts" > "Custom Shortcuts". Click the "+" and add the command above to a shortcut you like.
This works nicely, but there is a small chance that if your system is heavily occupied, the window will not appear in time so the
xdotoolcommand will run in vain. Writing a separate script to prevent this from happening once a year seems overkill though in this situation.
Window placement is handled by
compiz in Unity and to fine control it's behaviour, you need to install
ccsm or compizconfig-settings-manager.
Install it with this command
sudo apt-get install compizconfig-settings-manager
Open it and go to Place windows plugin page. Under the section Placement mode select Centered to have the desired effect.
The default selection is smart I think. You can also try Cascade which is the default case in Windows systems afaik.
