Ah damn, went over the line limit thanks to clippy. I'll look into that tomorrow.

[NickGeek]

Hmm, I've found a bug when the status bar line goes >1 row in size the main text buffer's view breaks a bit.

Edit: fixed!

Sorry for the delay, I'll review this very soon!

Thank you, this is a great change!

[ilai-deutel]

Should it be

Suggested change

	(wsize.0.saturating_sub(1 + (self.status_msg().len() + wsize.1) / wsize.1), wsize.1);
	(wsize.0.saturating_sub(1 + (self.status_msg().len() + wsize.1 - 1) / wsize.1), wsize.1);

instead? Currently, 1 + (self.status_msg().len() + wsize.1) / wsize.1 is equivalent to 2 + self.status_msg().len() / wsize.1

[NickGeek]

Hmm, not quite sure how to fit this one one line with this change + keeping rustfmt happy.

[ilai-deutel]

I think you need at least one extra line

-        (self.screen_rows, self.window_width) =
-            (wsize.0.saturating_sub(1 + (self.status_msg().len() + wsize.1 - 1) / wsize.1), wsize.1);
+        self.screen_rows =
+            wsize.0.saturating_sub(1 + (self.status_msg().len() + wsize.1 - 1) / wsize.1);
+        self.window_width = wsize.1;

At least until div_ceil is stabilized :)

I just merged #229, which cuts down the total line count, so that should be fine now
