Today, I download the new version mailwasherPRO v7.12.38, but the email account password still can be viewed easily by pressing the EYE icon.
For this reason, I could not install mailwasherPRO ver 7 on another colleague's computer or let another person check and delete some mails for me. He/she will easily know all my email account passwords.
Please do consider to disable this function. With reference to your mailwahserPRO version 6, once you input the email account password on the setting, there is no EYE icon to show the password. This is for security. For example, on the outlook 2013/2016 or the iPhone, after you save the password, no one can view the email account's password.
