A new update to Acorn is out, version 7.4. I've added clone tool improvements, you can now assign a corner radius to bézier curves and star shapes, the color picker now allows you to use float values for the RGB values (so you can get super, super accurate with your colors), and some new command bar actions and AppleScript abilities. There's more as usual, and you can check the full release notes for the details.
While working on Acorn 7.4 I kept on glancing at the version number and wondering why it felt so… familiar and right to me? And then it eventually hit me — I was born in '74. So I really like this version for that reason alone. I think any future big features will be stuffed under the 7.4.x number instead of a 7.5, just so I can keep the '74 around longer. I mean, why not? It's my app and I can do that.
