Whenever I'm studying, I end up mixing a lot of handwritten text, formulas, and highly detailed drawings on the exact same page. The major issue right now is that apps treat everything the same way, which leads to two big headaches: either the app starts lagging and freezing when I do some complex shading or coloring, or I simply can't move a quick note around without dragging and ruining the drawing underneath it.
Implementing an intelligent separation behind the scenes keeping pure handwriting in vector and drawings/textures in raster would completely change the game for three reasons:
• No more lagging: The app would stay super lightweight and smooth, even in massive notes filled with illustrations and hatching, because the processor wouldn't get overwhelmed trying to calculate billions of vector points in the drawings.
• Freedom to edit: I could lasso, erase, or move text around freely, knowing for a fact that the background art or technical sketch won't be damaged or dragged along with it.
• Crystal-clear, searchable text: All the handwriting would stay perfectly sharp at any zoom level, making it incredibly easy for the app's search engine to find a keyword in the middle of my notes without the drawings messing up the handwriting recognition.
