"Show tabs for screens" doesn't show separate I/O tab on OSX

[monochromec]

When configuring htop on OSX to show I/O traffic in a separate tab via "S" in htop, the only tab visible is still "main".

htop version: htop 3.4.0-dev (installed via homebrew)
OSX: 15.4 running on Apple silicon

Please let me know if more information is required - more than happy to help.

There is only one screen defined on Darwin:

htop/darwin/Platform.c

Lines 67 to 75 in 325e6a4

	const ScreenDefaults Platform_defaultScreens[] = {
	{
	.name = "Main",
	.columns = "PID USER PRIORITY NICE M_VIRT M_RESIDENT STATE PERCENT_CPU PERCENT_MEM TIME Command",
	.sortKey = "PERCENT_CPU",
	},
	};
	const unsigned int Platform_numberOfDefaultScreens = ARRAYSIZE(Platform_defaultScreens);

Any particular reason for this constraint?

Is extending this on the feature roadmap?

The necessary I/O columns aren't available/implemented on Darwin.

No.
