removal of rounded project corners with an option

i think this would be nice because the rounded corners cause a lot of problems for me.

-Recording
Its hard to get a square recording with the rounded corners

-Sprites
if there is a sprite at the corner of the screen and the corners are covering it, thats a problem

-Costume Editing
Just hard to line up a box with those corners

-ugly
for me its just plain ugly

Keep in mind this can be an option in account settings and not a requirement

support. Projects like https://scratch.mit.edu/projects/296724684/ use the entire area and the characters at the corners are ever so slightly cut off, and as you said it faciliates recording/screenshots.

Support only if the default is set to rounded corners.

I like the fact that you're considering this as an option. It would be nice to customize the stage for those who need it. But the Scratch Team made rounded corners for a reason, and so it just makes sense to make rounded corners as the default option.
