This is caused by DeepSeek's lazy loading behavior, it doesn't load the full chat history until you scroll up to it. I've added a "Load all history when opening a session" option in the settings, which is off by default for now. When enabled, "Select all" will correctly pick up all messages in long sessions.

I'll be testing whether the Load All History setting causes any performance issues. If it's fine, I'll make it the default.

Note: For now, even though "Select all" correctly selects all messages with the setting enabled, you might still see some empty checkboxes in the UI. That's just a visual issue.

Try refreshing the page after enabling the setting, it needs a reload to take effect. If that still doesn't work, could you open the browser console (F12) and let me know if you see any related errors?
