TemplateTree 4.0 fixes template insertion in iframe-based editors, including embedded email compose fields. The extension now detects editable targets inside nested frames and injects the content script across all frames for better compatibility.

Improved text insertion reliability in complex web forms and editors.

What changed in this version:

Fixed an issue where inserted template text could disappear after submit in some sites.
Improved compatibility with modern web app frameworks by triggering standard input/change events after insertion.
Enhanced insertion handling for textarea, input, and contenteditable fields.
Better support for nested/shadow DOM focused elements.
Kept existing templates and settings fully compatible for seamless upgrade.

Change the UI, use the simple style with black and white color only
