zentile VS terminator

You may also want to try xpytile https://github.com/jaywilkas/xpytile/ or zentile https://github.com/blrsn/zentile

I guess this should work for zentile but per https://github.com/blrsn/zentile/blob/master/config.go I am seeing just ignore, not window.ignore? That might be something you know better about. (ignore = ['ulauncher', 'gnome-screenshot'])

Not out of the box, but there's utilities like zentile that work on EWMH-compliant window managers to make them tile -- I'm not sure if elementaryOS's WM, Gala, follows that spec, but if it does then it should work.

No. But you can use zentile

Until recently, my answer would have been Terminator. Recently, however, the lack of support for OSC52 and the fact that the workarounds don't always work reliably has been bothering me more and more. Based on https://gitlab.gnome.org/GNOME/vte/-/issues/2495, it is quite unlikely that VTE (and therefore Terminator) will ever support OSC52.

For terminal software, I really enjoy using Terminator, because it allows me to spawn several tiled terminals in a single window, with a custom arrangement that can expand and shrink easily.

I use Terminator as terminal emulator and ZSH as shell.

Using a Terminal Emulator with native support for split panes (Examples: Terminator)

I use the ZSH as a shell with its own configuration. As terminal emulator I use Terminator. From my personal point of view I don't need anything more modern.
