- Make there be a border at the outside on both the left and the right
- For the inner dividing borders, use left instead of right so that
there's a slight gap between the left-aligned text and the border.
Don't dim the highlight sides on hover. I feel like that makes it feel
like it's disabled. But don't dim the center as much, so the highlight
doesn't _stand out_ when hovering.
I've settled on underscores, for now at least.
Generally I use hyphens.
Built-ins actually use hyphens, like `.-dark-mode`.
Maybe I should be using hyphens.
But for now, consistency is what's important, and I'm using underscores.
It's a bad idea, unless applied on a case-by-case basis.
It makes things wrap badly when the viewport is narrow, making things
much less readable, even though the aim is to make it more readable
by ensuring visibility. And it makes message boxes feel less OS-like.
It's better to have to drag a window back and forth to read it, than
to have it wrap at every character.
- Confirm discarding changes for Open, New, or Exit, including for
exit via Ctrl+C which was previously handled by a built-in binding.
- Await Save As dialog closing, including when Save triggers Save As.
This is my first time using asynchronous features in Python,
(as far as I remember,) so it's a bit messy.
- Make DialogWindow callback also for Cancel, which means all
DialogWindow usage sites care what button is selected.
- Send RequestClose event for Esc key.
A Textual layout bug is unfortunately making the Yes button HUGE,
and the No button INVISIBLE, until you mouse over the dialog, which is
pretty funny...
"<file> already exists. Do you want to replace it? [Yes]"
Ideally it would be nice if you could access everything, but it's not
part of the design of MS Paint, and I don't want to design for it here.
In MS Paint, there's a minimum window size.
