[Feature Request] Add PS-style Pen Tool & Office-style Freeform Polygon Tool

[fireflysss]

I appreciate this great tool! When drawing free shapes, the current Bezier/polyline tools have pain points: need to drag first, 8-vertex limit, unintuitive operations inconsistent with PS/Office. I suggest adding a PS-style Pen Tool (click canvas to create anchors, adjust curves, shortcut for point conversion, auto-close) and an Office-style Freeform Polygon Tool (click to add vertices, double-click to close, Shift for angle constraint), remove vertex limits. If new tools are unavailable temporarily, optimize existing ones to support direct canvas drawing.

Hope the suggestion is adopted!

📝 Additional Information Needed

To help us investigate this more effectively, could you please provide:

• Are there specific drawing workflows or use cases where the current 8-vertex limit particularly impacts your work?
• Would improving the existing Bezier tool to be more intuitive (e.g., click-to-place without initial drag) be sufficient, or do you specifically need separate PS-style and Office-style tools?
