Add a lasso tool

First of all, thank you for creating such a lightweight and handy application, it’s incredibly useful for quickly jotting down ideas and notes.

It would be great to have a lasso (selection) tool, similar to those found in standard whiteboard applications. This would allow users to select multiple elements and perform actions such as duplicating, resizing (scaling up or down), and deleting the selected elements, among other common operations.

I believe this feature would significantly improve usability and make the app even more powerful for everyday use.
