Better Drawing features on iPad

I like how drawing is implemented for iPad currently, but there is room for significant improvement, in ranking of (what I believe) feasibility:

- resizing, when a drawing object is selected, pinch to resize

- shapes (at least rectangle, circle, and line)

- make copy and paste work, for some reason, when I copy a drawing object, I can't seem to paste it. This might purely be on my end. (Duplicate does work, so this aint too bad).

- Infinite canvas

- OCR, recognize handwriting and make it searchable

- Attachment markup, markup attached PDFs (at least), and maybe images and powerpoint if possible

I take notes primarily on my iPad, which is great for math and physics, which require quick diagram making. I came from Notability, which was a great annotation software, but I love XMind for its portability and flexibility. I chose XMind over Obsidian for its drawing support. Would love to see drawing develop further :)
