cannot access hidden LXDE panel

Question

Thinking that CPU and RAM information would clutter the primary default panel, I decided to create a separate side panel to display it optionally. I then set the panel to hide at 0 pixels and can no longer access it.

Does the panel still have a config file somewhere so I can change the settings without being able to unhide it?

I know I can just make a new panel and not bother with the useless properties file collecting dust in some directory somewhere..

The config files for lxpanels should be found in the directory /home/uesr/.config/lxpanel/LXDE/panels/.

It looks something like the example below and should be pretty straightforward. To reload the config after editing, you must first kill lxpanel:
killall lxpanel

You'll notice the panels disappear and then you can start it with the new config with something like this (Note the trailing ampersand which will run this process in the background):

lxpanel --profile LXDE &

I say "something like this" because in this case my profile is called LXDE. However, if you look in the directory /home/user/.config/lxpanel/ you may see a few different directories. Each directory located in /home/user/.config/lxpanel/ is a profile.

From man lxpanel:

FILES
       ~/.config/lxpanel/PROFILE
           config file, can be edited by preference dialog.

For me, the output of ls /home/user/.config/lxpanel/ displays the following profiles(directories): default Lubuntu LXDE. Mine are in LXDE so I use lxpanel --profile LXDE & to run lxpanel.

Below is an example of a panel I have that just displays the clock plugin at the right side of the screen. The config file itself is /home/user/.config/lxpanel/LXDE/panels/left which is misleading since it's located on the right. Depending on how you created the panel, the name may not indicate the actual location of the panel so make sure you are working in the correct config file.

# lxpanel <profile> config file. Manually editing is not recommended.
# Use preference dialog in lxpanel to adjust config when you can.
