Scale Snap is a small plugin that allows the use of keys to scale parts precisely instead of dragging a handle with the mouse. You can download it here, and it’s also open-sourced here!
i’m guessing that’s because it copies your studio move increment and the smallest increment you can have is 0.01 (off) ? i’ll make a special case for that in the next update where 0.01 → 0.001
i feel like that might be a *bit* annoying if you’re trying to select faces (and soon multiple faces), though the plugin is open source and you can add that if you’d like!
thought about this some more: i think i’ll introduce a “fine precision” mode toggle that uses an increment 1/10th the size of your studio increment, so you’ll be able to do any number 0.001-0.01 instead of just 0.001.
