this one-liner adds aliases to quickly on/off dev_mode for OpenPanel:
bash <(curl -sSL https://gist.githubusercontent.com/stefanpejcic/9c2b7313c052ce5fdb2ab816f52ff08b/raw/591001785c3a42b2b5401a039e7207d161d99c34/add_opencli_aliases.sh) && source $HOME/.bashrc
then run:
devon to enable (executes: opencli config update dev_mode on)
devoff to disable (executes: opencli config update dev_mode off)
