I am making a web browser, and I'm using tabcontrols. I want to offer my users the option to save, and then reopen tabs they have open on next startup like Google Chrome. How would I go about doing this? I have a form that I am using as an options menu with checkboxes for the user to check if they want it or not. How would I go about coding this? Any help would be appreciated thanks!
