It's not a problem but would be an improvement to avoid misunderstandings

Describe the solution you'd like
I wanted to remap the stage_item/unstage_item to Spacebar instead of Enter, so I changed

enter: ( code: Enter, modifiers: ( bits: 0,),),    

to

enter: ( code: Char(' '), modifiers: ( bits: 0,),)

It would be nice if one could document how the x and y coordinates are defined. (Beginners might not know about it and well the more documentation the better).

What I think when I see x and y:

What it actually is:

I would like for an effect to render text (or ASCII characters) from left to right, like it's being typed out.

Describe the solution you'd like
Similar to the mirage effect (where text can be rendered one character at a time, only randomly), it would be cool to have text rendered one letter at a time from left to right, so

Vec2 is currently made of 2 usize. This means 16 bytes on x86_64, which is crazy.
A pair of u16 would probaby be enough (this puts a limit of 65k, or 32k if we used i16, which sounds enough). Or even u32/i32 would already halve the size.

The main issue is conversion with other types. We'll need to see when/how values are converted.

Currently we need to pb.Add(0) after a title change to a progress bar to update the title.

pb.Title = "Test"
pb.Add(0)
// Do stuff
pb.Increment()

⬇️

pb.UpdateTitle("Test")
// Do stuff
pb.Increment()
