are there external custom modules for bodhi 5.0 ???
 

???

Hello there

I am not sure I understand your question but probably you are looking for extra modules mainly like screen gadgets
If I am right, you can see the list of them here:
http://packages.bodhilinux.com/bodhi/pool/b5main/m/

Installing
sudo apt install moksha-module-name

Then go to the module section under settings, look up and load the right one
Go to the gadget section and place it on the screen (background). Adjust its size and position.

I hope this is what you needed
If not, feel free to ask

PS: in the future, please be more precise in question specifiaction. We need more info to help people.
