Does anyone know if there's a setting to boop these back to being two rows instead of three?

If I'm understanding correctly, you just need to disable the third hotbar under options>gameplay section, action bars. Gonna guess it's action bar 3, but edit mode would tell for sure.
I still want all the buttons, I just want them in two LONG rows as opposed to three shorts.
You could take the third bar and adjust the rows setting in edit mode and enable snap and line it up to the ends of the other two bars to hack it and just keybind it so it seems like they're two long bars. I don't think the base UI has any way to make them 18 rather than 12.
Yeah, any given bar has that max number of buttons allowed, but you can “append” two bars together to fake a longer one.
Yeah, if you're not seeing the option to change the button alignments, just click on the bar, and it should bring up an additional edit window
