yes i want to open 5 different wallets all at once .. too bad if not.. i think you can add parameters on a link but im not sure how to do it..
create a bat file, put 5 lines in there
electrum.exe -w WALLET_PATH1
electrum.exe -w WALLET_PATH2
electrum.exe -w WALLET_PATH3
electrum.exe -w WALLET_PATH4
electrum.exe -w WALLET_PATH5
place it in the windows startup folder
