UI/UX Suggestions Redesign

Hey there! First of all, let me thank you for this plugin, it had helped me a lot!
From my experience usage, I suggest a few changes to the interface to make it even better:

- Possibility to add multiple widths to import several designs at once.
- Possibility to have presets so the user doesn't have to type the width all the time.
- User interface closer to the native Figma experience

Example:


What do you think?

No source files, tests, or entry points are named. Start by locating the plugin UI and the current width-import flow, then compare the three proposed changes with existing Figma behavior. Done requires an agreed scope and acceptance criteria for multi-width imports, presets, and native-like UI; the issue alone does not provide them.
