Yes I know I'm technically on vacation but if I go too long without writing I die from a witch's curse and I don't want to work on longform projects For Reasons so here, have a newsletter post.
I take a lot of handwritten notes. This used to be with actual pencil and paper, but for various reasons I now use a Surface Go running OneNote. It's worse in some ways but better in just enough to be worth it. One thing I thought would be nice, but turned out to be fairly limited, is the "ink to shape" feature. You draw a freehand square and it converts it into a square shape. It's kinda janky, and doesn't always get stuff write, but it's often enough to be useful.
It will not convert things that look like straight lines into straight lines, or let you draw nice arrows. This makes it more limited than I want, making it less useful. Until yesterday when I was doodling and it suddenly turned a scrawled line into a line segment.
I experimented a bit and I can kinda get it half the time, except I have no idea why what I do works! You have to add a little glyph to the end, it seems, but what shape is the recognizer looking for? No clue. And can this give me arrows, too? Also no clue. I tried a bunch and didn't get any arrows, but I also tried a bunch for years to get line segments and didn't get those.
