Be able to interact by either:
/ [search-string]
> [change the executing cmd]

Monitor a specific file for changes.

e.g.
This would be useful when displaying a matplotlib-generated plot.

stderr will not be caught or checked for change, and so will be plopped continuously to the screen

Can use the logic of file-descriptor swapping.

Similar to the '/' command, only dont highlight, but "delete" the incoming lines.

The purpose of this is to simplify the output for the viewer.

Must also look to handle non-printing characters.

• post-cmd throttle (always 1s after)
• cmd runtime-inclusive throttle (1s - cmd-exec time)
• screen-size-change
• files changed

Must consider the best way to handle conflicting triggers.
Should it be an "and" or "or" or masking behavior?

Be able to turn-off ability to interact with the display-instance, for things like searching strings in the output.

'f' to freeze a pane, showing some indicator that the cmd is done

Usage:
--watch .
-or-
--watch-all

Be able to change, only, a regex fed into ack-highlight.
This would build a nice searchability into display.

Be able to dynamically edit the top-line, header item.

• truncate-height
• truncate-width
• --colors
• emulate tty (for colors)
• header, no-header
• timer

For the body:

• head
• tails
• head-and-tails

Here is a package which probably has a lot of the corner-cases considered and worked-out:
https://github.com/sindresorhus/string-width
... an npm package.
- strips color codes
- measures the length of 2-char codes

Disable any throttling or timing w/ gnu-date.

Run as fast as possible.
