I would like to suggest adding an "Erase Pen Only" option to the eraser tool.

Currently, we have useful options like "Erase Highlighter Only" and "Erase Tape Only," but there's no way to erase just pen strokes without affecting other elements. This feature would help users make quick and precise edits without removing highlighters or tapes.

I believe this small addition could significantly improve the user experience for many.
