You can (if you want that) even run different setups/electrums on the same device by combining the installed, stand alone and portable versions of electrum.
Electrum wasn't developed to fit just one type of person. I have never used an Invoice on Electrum. But I have also never clicked on it by mistake or just for the fun of it. I have never used the console tab either (can be switched on/off from the settings), but I have never accidently opened it when trying to generate an address. Just use the stuff you need and forget about those you don't.
