Negative values for Shape Roundness when refining a selection

What features would you like to see in Pixelmator Pro?

This afternoon I was trying to neaten up an old logo for which source files were unavailable. The logo was all tired and blurry. My process was as follows.

For each item:
1. Use Color Select to grab an object.
2. Use Refine Selection and Expand to get the outline exactly where I want it.
(edit) 2.5 Add a new layer.
3. Use Format > Convert into Shape to get a Shape.
4. Mess about with the control points to square off the rounded corners that resulted from the source being blurry.

I realised that it would be really useful if the Shape Roundness slider in Refine Selection could take negative values to make rounded corners more pointy. I have absolutely no idea if the current algorithm could be tweeked to do this or if it's a whole new bit of code. (I also have no idea where on a scale of 1 to impossible this lies). It certainly would be useful, though.

Hope you can help.

Thank you, Stef for being so active and your input (also you communicate very well) for bringing Pix Pro forward. Much appreciated

Heh, that's an interesting request — on a scale of 1 to impossible, it's a little too close to impossible for my liking. For one, how would it work with perfect circles, for example? I guess it could kind of work like corner radius does with a rounded rectangle, but why would it necessarily have 4 corners, rather than, say, 3 or 5? What about a weird shape like this:

So yeah, not sure if we can do anything about this feature... Sorry, Stef.
