Most non-tui programs being run in terminals don't operate that way though, and tui stuff resizes just fine. ps, for example, only outputs text to fill the terminal size and truncates the overflow (which is why it's not safe to grep). Not reflowing makes a lot sense when compared to the complication and bugs reflowing would bring.

It really is until you settle on a larger terminal size by default (I use 100x25 or 100x50 usually, sometimes 132x25/50 for lots of output.) I still miss it though. Don't know why they never added it, for example it's got a whole Tektronix emulator built-in so bloat and extra work are no excuses.
