This project is a simple desktop Kanban Board built with C# (WinForms).
It allows you to create, organize, and save tasks in 3 columns:

• To Do
• Doing
• Done

Each task supports:

• Title and description
• Deadline
• Priority (High / Medium / Low)
• Optional email reminder

• Add tasks with title, description, deadline, and priority.
• Drag & Drop tasks between columns.
• Save all tasks into a local file (tasks.json).
• Automatically load tasks when the application starts.
• Send email reminders for tasks with deadlines.

Email reminders are sent through Gmail SMTP.
⚠️ The sender and password must be configured directly in the code (EmailHelper.cs):

var mail = new MailMessage();
mail.From = new MailAddress("[email protected]");
mail.To.Add(to);
mail.Subject = subject;
mail.Body = body;

var smtp = new SmtpClient("smtp.gmail.com", 587)
{
    Credentials = new NetworkCredential("[email protected]", "your-app-password"),
    EnableSsl = true
};

smtp.Send(mail);
